Hello there. I recently was diagnosed with cellulitis. But a few days before that, my left heel hurt very badly to the point of not being able to walk. Then, I got this pain in one area of my spine, mid upper area. It feels as if it is bruised. These two pains have been bothering me for weeks. As I was on bed rest for the cellulitis, I woke up one morning to notice my right hip hurting, as if it's bruised inside when I touch it. Extremely painful when I sneeze for both the hip and back. And finally, I noticed a few days ago my right knee on the outside feels as if it wants to give out when I walk. Doctors checked the x-rays, nothing seems to be wrong
