Differentiating Between Oral Herpes and Canker Sores
Are you dealing with an oral sore and unsure if it's herpes or a canker sore? I’m a 25-year-old male who has recently relocated to a new state and am currently searching for a testing facility. The thought of possibly having herpes is quite daunting for me. I can’t share images here, but I want to describe what I’m experiencing. I have developed a sizable bump on the outside of my lip that resembles a canker sore. This bump is round and crater-like. Interestingly, it doesn’t cause any pain or tingling, yet I find myself picking at it out of sheer annoyance that it’s present. Upon reviewing some photos taken a couple of days prior to the bump being noticeable, I could see a tiny bump that gradually progressed to its current form. As I explore information about herpes, I’m realizing that my symptoms don’t align with typical cases. Most descriptions refer to clusters of small bumps filled with pus that eventually crust over, whereas I simply have the singular crater-shaped bump with no signs of oozing or scabbing. A challenge I face is the lack of visual references for herpes specifically on darker skin tones. I wonder if it would be possible to share an image for further insight into what this could potentially be. 🙏🏾

It sounds like you're feeling uncertain about the bump on your lip, and it's understandable to want clarity on whether it might be an oral herpes sore or a canker sore. While I can’t diagnose your condition without seeing the sore, I can help clarify the differences between these two types of sores and suggest steps you can take.
Main Points:
- Oral Herpes vs. Canker Sores: Understanding the key differences can help you deduce what you might be experiencing.
- Self-Care Tips: Managing the sore until you can get it assessed.
- Next Steps: What to consider as you search for a testing facility.
Explanation:
-
Oral Herpes (caused by the herpes simplex virus) typically presents as small clusters of fluid-filled blisters, often painful, which may crust over after a few days. These can occur on or around the mouth.
-
Canker Sores, on the other hand, occur inside the mouth and are usually round with a white or yellow center and red edges. They can be painful but are not caused by a virus and are not contagious. The bump you're describing on your lip sounds more characteristic of a canker sore, especially since it’s round, crater-like, and non-painful.
Next Steps:
-
Avoid Picking at the Sore: Although it's annoying, picking can lead to infection or prolong healing. Try to keep the area clean and avoid irritating it further.
-
Self-Care Measures:
- Rinse your mouth with salt water or a mild mouthwash to keep the area clean and reduce irritation.
- Apply over-the-counter numbing gels if you experience any discomfort, or use ice to cool the area.
-
Monitor Symptoms: Keep an eye on any changes - if the bump starts to ooze, becomes painful, or you develop fever or swollen lymph nodes, this would be a sign to seek medical advice more urgently.
-
Testing Facility: As you investigate testing facilities, look for local health clinics or STI testing locations. Online platforms may also provide STD testing options with discretion, and you can inquire specifically about herpes testing availability.
-
Educate Yourself: Consider reading reputable sources about oral herpes and canker sores for more insight. The CDC and Mayo Clinic offer clear, accessible information.
If your symptoms change, or if you're still worried, don't hesitate to seek medical advice when you have the opportunity. It's important to prioritize your peace of mind and health.

Liver Mass Assessment
Patient Profile: - Age: 61 years - Height: 5'9" - Weight: 240 lbs - Gender: Female - Lifestyle: Non-drinker, non-smoker, no illicit drugs Current Medications: - Atenolol 10mg (morning and evening) - Rosuvastatin 40mg (evening) - Duloxetine 60mg (evening) - Spironolactone 25mg (recently added) - Jardiance 10mg (recently added) Medical History: The patient has a notable history of multiple pheochromocytomas and paragangliomas, having undergone surgery on eight occasions. According to scans performed three years ago, two subcentimeter retroperitoneal masses were identified, suggestive of potential paraganglioma. Additionally, she suffers from secondary polycythemia and possesses the PHD1 gene mutation. Previously, she received treatment at a prominent research institution in the United States. However, her endocrinologist has since retired and returned to their home country. Current Condition: At present, she is mostly asymptomatic. However, in January 2026, she experienced a concerning event requiring an ambulance transport to a local emergency room, where her oxygen levels registered at 88-89%. This incident was unsettling, given her extensive medical history. The emergency physician initially diagnosed her with congestive heart failure (CHF), but upon discharge, her family medicine doctor suggested pneumonia. During her hospital stay, a cardiologist—who has never managed a pheochromocytoma patient—recommended a chemical stress test. A CT scan performed on her chest revealed a 3.2 x 2.5 cm mass located in the left lobe of her liver. Her blood tests typically show elevated levels related to pheochromocytomas; however, the laboratory does not conduct resting catecholamine testing, which leads to unreliable results, despite them being consistent over time. Furthermore, she has received care at major hospitals in Minnesota and both leading hospitals in Cleveland, Ohio. Unfortunately, when she required her last surgery, the tumor board declined her case, citing an unfavorable risk-benefit ratio. This leaves her without a specialist in pheochromocytomas. Request for Guidance: The patient is seeking advice or recommendations for her current health situation and management of her conditions.
Navigating the Complexity of Symptoms: Is It PCOS or Something Else?
While I’m not an expert in self-diagnosis, I find myself puzzled by an array of symptoms that overlap, making it challenging to pinpoint what might be affecting my health. Let's break down my situation: - Age: 25 years, Gender: Female, Height: 5’1”, Weight: 125 lbs. - The last menstruation occurred in June 2024. Prior to this, my menstrual cycle was remarkably consistent since I was around 12 years old, typically without severe premenstrual symptoms, heavy flow, or irregularities. - Various blood tests over time reveal that most hormone levels fall within normal ranges, with the exception of estradiol (persistently between 10-20) and progesterone (remaining below 0.2). - A couple of results raised some concerns for me personally, even if my doctors weren’t alarmed: my morning cortisol was measured at 13.4 and in the afternoon at 9.49. One test indicated a TSH level of 2.35, which increased to 3.93 months later. My fasting glucose consistently hovers around 80, whereas random glucose levels were recorded at 68, and postprandial glucose was 65. - An MRI indicated a "deviation of the pituitary stalk, potentially linked to a small pituitary adenoma." - An ultrasound revealed "multiple oval, well-defined, anechoic images with posterior acoustic enhancement, measuring a few millimeters, located around the edges of the stroma." - The symptoms I am experiencing include disrupted sleep (frequent awakenings, particularly around 3 AM, making it hard to resume sleep), lack of energy, difficulty in weight management, persistent hunger, heightened anxiety, and hair thinning. - Birth control (drospirenone and ethinyl estradiol) exacerbated nearly all of my symptoms, leading me to discontinue use after two weeks despite experiencing a withdrawal bleed. - My lifestyle is generally healthy; I consume a lot of whole foods, engage in weightlifting, and run regularly. Given that I’ve received a diagnosis of PCOS, I’m wondering if this assessment seems accurate. What options do I have moving forward, especially since the contraceptive method didn’t provide relief and I appear to exhibit signs of additional complications such as thyroid issues or cortisol dysregulation?
A Mysterious Illness That Resembles Strep Throat
As an 18-year-old college student, standing at 5'4" and weighing 140 pounds, I maintain an active lifestyle. I do not smoke or have any preexisting health issues, aside from the vitamins and supplements I take daily. Approximately five days ago, I began to feel unusually fatigued and achy. Within just a day, my symptoms escalated to include a high fever reaching between 101°F and 102°F that ibuprofen couldn’t seem to alleviate. I experienced extreme tiredness that kept me bedridden all day, along with a persistent headache and intense throat pain, which was compounded by swollen lymph nodes and the familiar white patches often associated with strep throat. Having dealt with strep throat before, I recognized a need for antibiotics. Two days into feeling unwell, I visited an urgent care facility for an assessment and received a rapid strep test, which unfortunately came back negative. I recalled a previous incident where my rapid strep test also indicated a false negative, only for the culture sent for further testing to confirm the presence of strep bacteria. Given my symptoms and the findings from the examination, the healthcare provider prescribed Cefdinir, as I am allergic to amoxicillin, despite the negative rapid test results. The antibiotics proved effective, and I felt nearly back to normal, leading me to believe that my culture results would also come back positive for strep, suggesting a recurrence of my previous infection. However, I received the culture results yesterday, and to my surprise, they came back negative for strep. While I lack medical expertise, I’ve been led to believe that false negatives in cultures are exceedingly rare. Now, I find myself puzzled about what kind of bacterial infection I might have had if it wasn’t strep. Any insights or information regarding my situation would be greatly appreciated. Thank you!
Bleeding Concerns with IUD and Yeast Infection Treatment
I’m a 20-year-old female, standing at 5’4” and weighing 155 pounds. Hello everyone! Approximately three weeks ago, I had the Kyleena IUD placed, and everything felt fine afterward—I can still feel the strings. I noticed some mild spotting that was brown for about a week, followed by my menstrual period, then continued with light spotting. Recently, I suspect that I might have developed a yeast infection, which I am currently addressing using Monistat 7. I applied the first dose yesterday. To clarify, I am certain that I am not dealing with a sexually transmitted infection. However, I’ve observed an increase in bleeding, significantly more than what I’ve experienced before. The blood appears to be light red, and I would compare the amount to the lightest day of my period. I could comfortably go an entire day without needing to change my pad, though I still do it for hygiene reasons. Is this a common occurrence? Most of the bleeding took place this morning after I woke up, coinciding with the Monistat cream leaving my body. Under what circumstances should I seek medical advice regarding this issue instead of waiting to see how the treatment progresses?
Understanding Recurrent Symptoms: Are They Histamine-Related?
Hello, health professionals, I am seeking your expertise regarding a variety of symptoms I have been experiencing intermittently over the years. While they appear linked, I'm having difficulty pinpointing their root cause. **Personal Summary:** - 27 years old, Female - Non-smoker (formerly vaped for about eight years, cessation initiated two years ago) - No diagnosed autoimmune conditions - Background of anxiety (which might exacerbate some symptoms, though it doesn't account for all) - Currently taking Flonase and a multivitamin **Skin Reactions:** - I've dealt with recurring itchy rashes and hive-like bumps since childhood. They manifest suddenly and usually resolve without intervention. - These rashes are often itchy, can be raised, and tend to appear sporadically without identifiable triggers. - Antihistamines provide consistent relief, leading me to suspect a role of histamines in these eruptions. - These episodes do not align with typical contact allergies or classic food allergies. - They can happen multiple times daily, and I've often dismissed them as merely anxiety-related rashes. - Sometimes the itching precedes the visible rash, while other instances present with a red, inflamed area that stirs inquiries about my well-being from others. **Foot Discomfort:** - Over the last few years, I’ve encountered severe itching on the soles of my feet. - These episodes typically include small pale or white spots with redness surrounding them, occasionally featuring a red center. - Itching intensity can be overwhelming, yet these lesions usually arise suddenly, - They frequently improve upon avoiding scratching and may resolve within a range of 30 minutes to two days. - The first episode was triggered after swimming in a freshwater lake, though I’ve also experienced it while wearing specific footwear like Crocs or boots, but not consistently. - Certain events coincide with my typical skin rash, hinting at a potential systemic condition rather than merely a localized issue. - The symptoms do not mirror those of warts, ringworm, or fungal infections. **Ear and Sinus Issues:** - Itchy ears have been a recurring issue for the past few years; I initially attributed it to overly aggressive cleaning with cotton swabs, which I realize is harmful. - I have a history of chronic sinus problems, including post-nasal drip and regular ear infections. - The inflammation appears to flare up sporadically rather than constantly. - Recently, I experienced a painful ear issue that began with what I thought was a pimple. The next day, my ear was swollen. After visiting a clinic, I was diagnosed with a double ear and sinus infection, treated with antibiotics. My pain persisted, leading to a follow-up with my primary care physician, who prescribed Flonase and noted ongoing nasal inflammation. Missing doses led to increased ear discomfort, prompting me to take Flonase more regularly. Unfortunately, a recent flare of swelling and discomfort in my ear led me to consider consulting an ENT specialist. **Gastrointestinal Symptoms:** - I was diagnosed with gastritis through an upper endoscopy procedure. - Testing for H. pylori returned negative. - I've since developed food sensitivities and gastrointestinal discomfort not previously experienced. - I saw significant improvement after removing gluten and dairy from my diet, with tests for celiac disease yielding negative results. - Symptoms tend to flare up in response to stress or specific food intake rather than being a constant presence. **Additional Context:** - A history of childhood asthma (now occurs infrequently) - Sensitivity to heat - Past instances of feeling lightheaded, resembling vasovagal symptoms, alongside vertigo - Symptoms across various systems often flare together, but not in every instance - While my anxiety can intensify symptoms, both antihistamines and diet modifications have had notable positive effects **My Inquiry:** While I don’t wish to self-diagnose, I'm curious if my range of symptoms might suggest: - Histamine intolerance - Mast-cell overactivity (not necessarily MCAS, but an increased reaction) - Physical or contact urticaria I'm primarily seeking: - Recommendations for a suitable specialist - Insight on whether this symptom pattern fits a recognized mechanism - A clearer understanding of what warning signs to be concerned about **Summary:** I contend with a long-standing pattern of episodic itchy rashes and hives, significant but transient foot itching along with bumps, persistent ear irritation coupled with sinus problems, and gastritis accompanied by food sensitivities that improved on an elimination diet. Antihistamines aid multiple symptoms. Could this suggest underlying histamine-related issues manifesting across multiple systems rather than in isolation?
