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.

Dealing with Esophageal Cramping and Heartburn while on Oral Minoxidil
Hello everyone. I’m a 37-year-old male who frequently experiences alopecia areata, particularly during stressful periods at work. Recently, my dermatologist recommended oral minoxidil in 2.5mg capsules to speed up my hair restoration process. Since I began this treatment, I’ve encountered several side effects, including elevated heart rate, dizziness, shortness of breath, heartburn, and esophageal cramps, albeit not all at once. Most of these issues have subsided, but the cramps and intermittent heartburn persist. I find the cramps tend to occur after meals, accompanied by a sensation as if I can feel the food moving through my esophagus; this uncomfortable feeling can linger for hours before fading, only to return with my next meal. The discomfort isn’t severe enough to incapacitate me, but it can be quite bothersome, with some days being better than others. Should I consider halting the medication, or should I wait until my next scheduled appointment to discuss this? I live in a rural area, making it difficult to find sooner availability, as the next appointment isn’t for another month. I appreciate any advice you might have!
Excruciating Nerve Sensitivity
Greetings, everyone. I recently underwent surgery to address a cervical rib issue on the left side, utilizing the transaxillary method. Today marks ten days since the procedure was performed last Wednesday. I was discharged from the hospital Saturday morning and felt fine initially, aside from the typical discomfort associated with surgery such as pain, numbness, and some swelling in my left arm, which limited mobility. My surgeon assured me this was normal. However, come Monday morning, I experienced a sudden sensation that I initially thought was pain in my left hand, predominantly affecting my pinky, ring, and middle fingers, extending to my arm and shoulder. A visit to the doctor clarified that this was not just pain—I was experiencing hypersensitivity, specifically involving the ulnar nerve. A week has passed, and the intensity of the hypersensitivity is unmanageable. It feels as if my hand is simultaneously being burned, stabbed, and electrocuted. I have been prescribed medication like pregabalin, yet it only provides temporary relief lasting no more than an hour or two. While the swelling in my arm has subsided, the hypersensitivity and numbness continue unabated. Although I can move my arm and hand to a degree, my strength is noticeably reduced, which may be a lingering effect from the surgery. I was concerned there might be a hematoma at the incision site irritating the brachial plexus, but an ultrasound revealed no signs of blood accumulation. I'm currently in a challenging predicament and would deeply appreciate any suggestions or remedies you might offer, as the discomfort has become unbearable; at this point, I'd even consider amputation of my arm over enduring this agony.
Understanding Post-Surgical Pain After Ganglion Cyst Removal
I’m 17 years old (female, though I prefer He/him pronouns) and I have Ehlers-Danlos Syndrome (EDS) along with Dysautonomia. Currently, I’m not taking any medications that might impact my situation apart from an SNRI and birth control to manage cramping. Around a month ago, I underwent surgery to remove a ganglion cyst located on my dominant wrist (the right one). This cyst had been present for roughly three years, and despite my doctor attempting to aspirate it, the procedure was unsuccessful due to its firmness, leading to surgical intervention. This cyst significantly limited my wrist mobility. Now, after approximately four weeks post-surgery, I can say that my wrist is mostly improved. The scar is healing fairly well, and I’ve regained about half of my wrist’s mobility compared to the left one. Yet, I still experience significant pain when I move or apply pressure on the area that housed the cyst. Is this pain considered normal? Additionally, my fingers are in constant discomfort, and my wrist seems to dislocate frequently. Due to my EDS, I am accustomed to joint pain and dislocations, but this particular pain feels more severe than what I usually endure. When I brought this up with my surgeon, he dismissed my concerns, stating that such dislocations are common for individuals my age. However, I experience dislocations at least twice daily, and the process of resetting them creates such a loud sound that I've been asked to leave classes to avoid disturbing others. Is this normal? Could it be related to the cyst? Moreover, about four days ago, I noticed a small lump forming on my wrist just above the surgical area. When I consulted my doctor about it, he informed me that it was a benign fatty tumor and assured me it wasn't a serious issue. However, I've never encountered anything like this before, and while the lump is not painful, soft, and relatively small, I’m puzzled about its sudden appearance. Why did this occur, and what could explain my doctor’s nonchalant attitude towards my symptoms? I understand that experiencing pain and limited mobility after surgery is not unusual, but given my doctor’s dismissive approach towards my concerns, I felt compelled to seek insight here as well. He often seems skeptical about the symptoms I report, making it difficult for me to fully trust his evaluations.
Concerns About Changes in Partner's Semen Consistency
At 19 years old, I’m seeking some insights regarding a situation. My girlfriend, who is also 19, has experienced a noteworthy change in her semen consistency during our intimate encounters over the last two to three weeks. To provide some background, she stands at 5 feet 5.5 inches tall and weighs approximately 130 pounds. Her ethnicity is Caucasian, and she is from Canada. Historically, my girlfriend has been in good health without any significant medical conditions. Currently, she is not taking any medications. Previously, she had a history of frequent vaping, but that was about a year ago, and now she limits it to occasional use. The change in her semen is quite striking; it appears very thick, white, and somewhat chunky, rather than being mostly liquid. There are some liquid components, but the thick texture predominates. Throughout this period, she has maintained her regular diet, and importantly, there are no signs of a urinary tract infection or sexually transmitted disease. Neither does she experience any pain or unusual odors. This alteration has raised some concerns for her, and while I am trying to be supportive, I am uncertain about the potential causes. We searched online for explanations, but the reactions we found mostly related to digital sources that discussed various infections or medical conditions, none of which seemed to match her symptoms. Does anyone have insights or similar experiences regarding this matter? It would be appreciated in easing her worries and determining the best course of action.
Seeking Answers: Unexplained Symptoms
Profile Information: - **Age**: 15 - **Gender**: Female - **Height**: 5'3 - **Ethnicity**: Caucasian **Medication Regimen**: - Lisdexamfetamine: 40 mg daily - Famotidine: 20 mg, twice daily - Cetirizine: 40 mg daily I have been experiencing persistent pain for as long as I can recall, even before I started taking any medication, so I am skeptical about the drugs affecting my condition. Below is a compilation of my symptoms that I can remember offhand. My family has been advised on multiple occasions to consider testing for Mast Cell Activation Syndrome (MCAS) due to the alignment of my symptoms with the condition. My latest physician conducted laboratory tests to evaluate my tryptase levels without an initial baseline measurement. This was taken roughly 1.5 hours post-flare-up, which came back low. Consequently, she concluded that I do not have MCAS, but after researching further, I found that low levels do not definitively rule it out. I am reaching out for guidance—can anyone assist me in understanding my situation? **Presented Symptoms**: - Persistent hives - Facial flushing - Cognitive fog - Recurring headaches - Abdominal discomfort - Irregular bowel movements (ranging from diarrhea to constipation) - Anxiety attacks - Low blood pressure - Episodes of dizziness - Rapid heartbeat - Chronic fatigue - Episodes of fever - Severe joint pain - Night sweats - Bloating - Elevated sensitivity to sunlight - Intolerance to heat I frequently experience multiple symptoms together during flare-ups, with at least one flare occurring daily. The hives tend to emerge 1 to 3 times each day, primarily triggered by sun exposure and heightened emotional states, although at times they arise with no apparent cause. These flare-ups can occur abruptly, lasting anywhere from 15 minutes to several hours.
