i am 37 years old, 5 3 and weigh approx. 150lbs. I have a lump in my armpit. I have had it for a very very very long time. It usually is very small and doesnt hurt, about the worst usually is it kinda gets in the way of shaving. lol. But twice now (starting two days ago being the 2nd time) it suddenly swells very large and hurts pretty bad plus it slowly leaks this fluid that is kinda like snot. Im not sure if it that stuff that smells bad, or the fact that its hard to actually clean the area during this and i just have bad b.o. i m afraid its something bad....what should i do? or what the hell is it??
