question: I noticed it yesterday a lump in my left leg not so close to my pelvis area kind of lower and is swollen now, red color, painful, but I had a pain a week ago on the same leg but in the back of my lower leg by the fibula area. I have a pain and what shoul I take my dad gave me diclofenac because I always suffer from muscles pain...I was diagnosed like eight years ago with a slipped disc.Any advises?? thank you
