I have pain in my left side, in and around my hip, worse when I spend time sitting, and sometimes if I sleep on that side, I stiffen up and have difficulty getting up, Not a sharp pain more like a throbbing ache, my Dr only thinks it is a pulled mussel but have had this problem for almost 4 months. would really like some ideas to make it feel better or solve the issue, can you tell me any ideas for what the problem might be?
