Seeking Insights on Frequent Canker Sores
For the past year, I have experienced severe canker sores almost every month. At times, I end up with two or three sores simultaneously, and the healing process seems to take quite some time. I have been curious whether this condition might indicate a potential sexually transmitted infection (STI), but I always practice safe methods for any sexual activity, including both vaginal and oral encounters. I would appreciate any input or thoughts on this matter. Thank you!

Canker sores, also known as aphthous ulcers, can be persistent and painful. While they are often caused by factors such as stress, dietary deficiencies, or oral injuries, they are usually not linked to sexually transmitted infections (STIs). Your practice of safe sex also significantly reduces the risk of STIs.
Explanation:
Canker sores are not contagious and are different from cold sores, which are caused by the herpes virus. Common triggers for canker sores include:
- Nutritional deficiencies (like vitamin B12, iron, or folate)
- Stress or hormonal changes
- Certain foods (like citrus fruits, chocolate, or spicy foods)
- Oral injuries from braces or dental work
Given that you've had frequent and severe outbreaks for a year, it's essential to manage this condition effectively while understanding its potential triggers.
Next Steps:
-
Dietary Considerations:
- Review your diet for any possible deficiencies, particularly in B vitamins, iron, and folate. Consider incorporating foods rich in these nutrients, such as leafy greens, fruits, nuts, whole grains, and lean proteins.
-
Track Triggers:
- Keep a diary of your canker sore occurrences. Note when they appear, their severity, and any potential triggers (like stress or specific foods). This can help you identify patterns or causative factors.
-
Stress Management:
- Engage in stress-reducing activities like regular exercise, yoga, meditation, or any hobby that relaxes you. Stress can exacerbate the frequency of outbreaks.
-
Oral Care Routine:
- Maintain a good oral hygiene routine that includes a soft-bristled toothbrush and gentle mouthwash. Consider rinsing with warm salt water to soothe existing sores.
-
Over-the-counter Treatments:
- Use topical treatments such as benzocaine or aloe vera gel on the sores to relieve pain and promote healing. Products designed to coat the sore may also be beneficial.
-
Monitoring:
- If you fail to see any improvement or if your symptoms worsen, consider an evaluation of your overall health. This could include checking for other underlying conditions that could be contributing to the frequency of the sores.
If you feel concerned about the sores or their connection to other health issues, it may be beneficial to discuss this with a healthcare professional when possible. Let me know if you have any other questions or need further guidance!

Persistent Skin Rash Following a Hickey Received Three Years Ago
This situation has been quite perplexing for me and I’ve been trying to make sense of it. Three years ago, I received a hickey from a guy I never interacted with again, and shortly after, it transformed into a rash. Over the last three years, I've experienced recurrent flare-ups of this same rash in the identical spot on my neck. I do have eczema, but I find it strange how the rash continually reappears at the exact location of that hickey, which had never bothered me prior to that incident. Is there anyone who can reassure me that these occurrences are unrelated and merely coincidental?
Persistent Pain on the Right Side of Abdomen and Back
I’m a 32-year-old female weighing around 230 pounds and standing 5 feet 1 inch tall. My current medications include Vyvanse, Buspirone, guanfacine, and hydroxyzine to manage ADHD and anxiety, along with metformin for polycystic ovary syndrome (PCOS), omeprazole for gastroesophageal reflux disease (GERD), and a multivitamin along with inositol supplements. Recently, I underwent a bilateral salpingectomy in November 2024 and had my gallbladder removed just a month ago; however, the pain I’m experiencing predates the gallbladder surgery. I find myself in a frustrating situation, particularly because my surgeon declined to perform any scans prior to the gallbladder removal, insisting that my discomfort was entirely related to my gallbladder. For the past six months, I have been suffering from persistent pain located somewhere on the right side of my abdomen and/or back. I emphasize *somewhere* due to the fact that the pain seems to shift with my movements and does not follow a predictable pattern. Currently, the discomfort is centered in my mid-abdomen, near my lower ribs, but not long ago, it was around my hip area. Even now, as I type, sitting up straight has caused the pain to transition from my abdomen to my back, precisely in that same region. Massage therapy provides some temporary relief; the pain feels dull and achy, and I have that sensation that it yearns to be massaged. Unfortunately, standard pain relief medications have little effect. After my gallbladder surgery, the pain seemed to diminish briefly, likely masked by the more intense post-operative discomfort, but it returned within a week, persistent as ever. In addition to the pain, I’ve experienced intermittent nausea (which is usually linked to my anxiety) and severe diarrhea that began after the gallbladder removal. According to my surgeon, my gallbladder was indeed very inflamed and full of stones, affirming its necessity for removal despite any uncertainty it may have contributed to my pain. He also mentioned that it was adhered to my abdominal wall, which raises questions about possible relevance. Unfortunately, shortly after my surgery, my doctor stopped accepting my insurance, which has hindered my ability to secure follow-up appointments or discuss my ongoing pain with him. I am currently attempting to find a new physician, but there are limited options available at the moment.
Concerns Over My Friend's Spinal Cyst
My friend, a 25-year-old woman, recently learned she has a sizable cyst near her spine. The physician informed her only that the cyst is "large" and poses severe risks, such as the potential to cause paralysis or even be life-threatening if it ruptures. However, the doctor did not recommend surgery, citing the operation as risky with a possibility of recurrence. This particular healthcare provider has often been somewhat indifferent towards her, which worries me, especially given her keen intelligence. I am left questioning the level of danger she may actually face and whether she should seek further evaluations or other medical opinions. My friend meets nearly all the criteria indicative of Ehlers-Danlos Syndrome (EDS), although I'm uncertain how that condition might influence her situation.
A Regrettable Accident Involving My Knee
A 22-year-old male here, and I find myself in quite a predicament. While foolishly handling an antique revolver, I accidentally discharged a .32 S&W (black powder) round into the area just above and to the left of my knee. In the aftermath, I cleaned the injury, dressed it with gauze, and applied gentle pressure. Fortunately, the bleeding was minimal. I am currently keeping my leg elevated and using ice packs at intervals. Although there is no visible exit wound and I cannot feel the bullet, my kneecap is throbbing with pain, rated at about a 6 out of 10. To complicate matters further, I am a convicted felon, which prohibits me from possessing firearms. Although the revolver is technically an antique and isn't registered, I am hesitant to seek medical attention due to the potential police involvement. It's been roughly 10 hours since the incident, and there is noticeable swelling along with slight redness around the affected area. Aside from reminding me of my foolishness, what constructive advice can you offer in this situation? Is it likely that my knee will heal on its own? Would it be possible to get an x-ray later without the risk of police questioning? Thanks in advance for any guidance you can provide!
Are My Stitches Healing Properly?
Hello everyone, I wanted to seek some advice. Earlier today, I underwent a procedure to have a cyst removed from my face, and the surgeon placed six stitches to close the incision. Just an hour ago, once I returned home, I noticed that the skin around the stitches seems to be tightening or pulling. I can’t help but think that if there were a serious issue, the doctor would have pointed it out before I left the clinic. This reassures me somewhat, but I’m still concerned. Given the challenges of scheduling an appointment with my doctor, especially since I live in a different area, I’m unable to visit right away. Any thoughts or experiences you could share would be greatly appreciated!
