There are two red lumps on my left armpit.

Patient: I have been having reoccurring lumps on my right armpit. They go away after about a week. And I usually get them once every two months. I go to the gym and I do take some supplements like whey isolate protein powder. I use antiperspirant. Could this be the reason why this has been happening. Also, is there a way to prevent them from occurring.

Symptoms: They are medium lumps. Hurt when I press on them.
