Yes when small. The white-heads acne are typical examples of an infected sweat gland/hair follicle, which is often painless when tiny/small. When coalescedd involving few together or enlarged is called a furuncle(picture here), and even larger (two or more furuncles) is a carbuncle which are commonly known as boils which can be quite painful and needs treatment. If you have trouble, consult doc. Good luck.

Stop Keflex. No possibility of any benefit from any antibiotic, only risks of bad effects. Probably no need to treat. See a dermatologist if it annoys you. If it grows larger it needs to be checked: suggest a different place. Usually this will be a small cyst in the acne family. If it becomes painful or larger then other things need be considered.

Had a infected sweat gland drained 2 weeks ago now I have a cord sticking out from underarm where the sweat gland was. Very painful to lift arm?

Keep follow up. Hi Logan, Sorry to hear you are feeling poorly. Sounds like you had an abscess drained and possibly your doctors packed the wound to allow it to continue to drain? Some pain is normal after this procedure but is your pain getting worse? Are you doing the dressing changes? Is it still draining pus? If you haven't followed up with your doctor since the drain, I think you should as soon as possible. Read more...
