I was been diagnosed with fibromyalgia several years ago. I m used to odd pains that come and go, but this morning I woke to swelling in the ball of my foot (particularly under the index toe ), light bruising and slight redness visible even on the top. Also, my feet are usually very very cold. They are now quite warm. Aside from the fibro, I also have osteoarthritis , but no other systemic illnesses.
