Have a pain in my left buttock. It felt like the round hip bone at the top of the thigh was acting like a sledgehammer against the hip socket. Rest, hot or cold packs, even pain killers like Norco and tylenol3 are having no affect on the pain. The pain continues to worsen. The med center doc thought I pulled a muscle and prescribed flexeril and rest. If I move just right, the flesh and muscles in that buttock elicit a scream from me and feel like it's folding up like an accordion. Any suggestions?
