Hi all, been a while since I posted (for some reason my HA seems to plague me less when I find I am out doing things more often and being more active, I guess when I run it makes *everything* hurt so I am less prone to noticing little aches and pains ) but this has got me all worked up to no end.

Anyway, I have had this pain under my arm for the last 3 weeks to a month or so. It's a weird sort of pain, so forgive my all-over-the-place-ness while I try to explain it well. Half the time I have it, it feels like it's on the skin.. almost like a burning, like I've cut myself and something got into the cut. The other half the time I have it, it feels like it's entirely internal, and when I press on it, it hurts. I have one small skin tag under that arm, I don't know if that could be in any way related but I figured I'd add it in just in case... it has never hurt or caused me any irritation or problems and as far as I know it hasn't changed any since I've had it. I swear I can feel a lump, although I'm not sure if it's actually there or I'm just convinced now that it is, but I'm PRETTY sure that it actually is. Some days it doesn't really bother me at all, but some days it hurts a lot more. When I first got it, I was due for my period that same week, so I wrote it off to potentially just being hormonal. Now, again, when I am panicking about it oddly enough, I am due for my period this week, which is probably why I am stressing about it again. Does anyone know what it could be? I have noticed that sometimes when I shave my underarms it feels a little tender, again, almost like it's on the skin. When I put deodorant on (I use that Secret Clinical antiperspirant stuff, if it matters) and I push down on it with that, it gets tender, again, like it's internal. It's really scaring me, any personal experience or insight or even reassurance would help at this point. Thanks all.
