"Ya Give Me Feva..". Just got over a rather lengthy illness, and my curiosity was pigued. Can anyone tell me what causes the arthritic feelings one gets when running a fever for a long time? Is there something being deposited in the joints, like when a diver gets the bends, or perhaps the muscles or tendons contract? I can't be the only one who wonders this, so rather than just looking up the answers, I thought I'd ask here so others can benifit.
