This has a long history to it. A lump popped up on the back of my shoulder over two years ago. It's about the size of a quarter, it is well underneath the skin, and it is not solid. At the time, I had it examined, and it was determined it wasn't cancer -- it was a funky fluid pocket or growth (I'm not sure which now) right near the joint. It is pinning a few tendons on the back of my shoulder, and infrequently gives me discomfort. I notice an odd pattern of it swelling up around the time of my periods.

In any case, recently it changed a bit, and I think instead of doing its normal swelling and then going back down, it's grown. It hasn't gone down in over two weeks, and now my shoulder is aching very badly. In fact, I'm achey all over. About the same time I noticed this, I noticed some pain below my jaw as well, although I have no idea if these two things are connected. I'm having numbness pain all over, in the oddest spots now.

I'm frustrated and confused. I've already had a number of weird infections this year -- impetigo and a UTI, which is unusual for me -- and I have no idea how everything is connected. In fact, I wasn't even sure which board to post this too, because frankly... I don't know what's wrong.

To boot, although I have insurance, my husband and I are... poor. We just can't afford medical bills. I'm afraid to go to the doctor unless something is really wrong (I was a real hypochondriac as a kid).
