A little over a month ago, a lump
started growing in my left armpit
. It was hot, tender, painful, and eventually about the width of a quarter. About a week later, it started decreasing in size, until it shrunk to about the size of a dime. By then it was no longer hot or painful, barely noticeable. Then at about 3 weeks it began growing again, not painful, but noticeably larger. After a few days, it started shrinking again. As of right now, it is currently increasing in size, but not extremely.
