For the past year, I've noticed joint pain, swelling and stiffness when I get my period. It's gotten gradually worse in my left knee to the point that I cannot straighten my knee for the first two days of my period and going up and down steps is difficult. Then it abruptly goes back to normal. My periods are also extremely heavy on days 2 and 3 with some clotting. I've also noticed some discomfort and pressure on my right side above my hip bone and what feels like a lump of tissue right above my hip bone. It's not painful, but it's uncomfortable. Has anyone experienced any of these symptoms/any advice?
