I have a small bump on the left side of my tongue that I noticed about two or three days ago. I also have a cold sore on my lip I was wondering if the two could be related? I suffer from health anxiety so this is making me think I have oral cancer

Don't jump to cancer: You are right to think about your health anxiety - and you'd be right to get that under control. There are psychotherapists who specialize in this type of anxiety - it's fairly common. But the probable connection is a virus (herpes) or something like that and you can ask your Dr or a pharmacist for symptom relief. Canker sores should go soon, so if it lasts - see your Dr. Best! ...Read more

Two problems: Let another doctor look at your lip if the scaly bump is always there. It could be precancerous but probably not in a 35 year old female. I would guess that the facial pain and swelling is unrelated to the lip, and i would believe the doctor on that one. ...Read more

I had a cold sore on my lower lip a year ago and when it healed a skin tag appeared. I have cut it off twice and it's coming back again.

I had a cold sore on my lower lip a year ago and when it healed a skin tag appeared. I have cut it off twice and it's coming back again.

That might not be...: ...a skin tag. It could be scar tissue. Every time you cut it off, it may be healing with more scar tissue. If it is a skin tag, it needs to be removed completely to prevent recurrence. I don't recommend self-surgery. Leave it alone, let it heal and make an appointment to see a dermatologist, an oral surgeon or an Ear, Nose & Throat doctor. ...Read more

My bottom lip is chapped, the skin that connects to my bottom lip is peeling. The last time this happened, I used Vaseline and got a cold sore. Idk?

My bottom lip is chapped, the skin that connects to my bottom lip is peeling. The last time this happened, I used Vaseline and got a cold sore. Idk?

Cold sore unrelated: I don't think that cold sore outbreak was directly related to the use of vaseline. Petroleum jelly (vaseline) actually is known to promote healing of damaged skin, since it helps 'seal in' the sensitive skin cells under the damaged area...then they can regenerate. Cold sores usually come out at times of stress- exams, break-ups etc, so I think this was unrelated. Best to keep stress to a minimum. ...Read more

I have a white patch on my bottom lip not sure if cold sore or not been there for 24 hrs no tingling no swelling yet i feel skin tightening around it ?

Lip Sore: Could be a cold sore. Could be from trauma to lip such as having been bitten. Chances are it will improve on its own, however, particularly if you are a smoker there always concerns for leukoplakia which may be a premalignant lesion. If it persists you should see your doctor. ...Read more

See dermatologist : Consult a dermatologist to see if you have an irritant dermatitis, viral infection, peri-oral dermatitis or other rash. Treatment will be based on the cause of the rash. If it is an eczematous dermatitis, it is often treated with a topical steroid. ...Read more
