I have researched this and know that it is not a hair follicle or sweat gland because as I mentioned I can move the skin over the lump. It is not a bug bite.
No. It is fixed and hard.
Yes. I noticed it washing under my arm in the shower. It was a little tender to the touch, but that seems to have decreased over the past few days, but the size seems the same.
The thing in my nose has been coming and going a for few years, a couple of times a year. I also have had infrequent cold sores on my lips since childhood.
What about the large cold sore type thing on my chin? That is new. It showed up last week, I treated it and it scabbed over and was fine, now it's back.
Okay. Last question, which antibiotic?
