|I have pain in my left lower back that is aggravated by sitting (this is a real problem as I have 4 hours of intense class for 4 hours every morning.). It is relieved by standing and lying down. While on my back if I try to stretch my right hamstring I get the pain. I can never seem to stretch the muscle and I don't get relief from muscle relaxers, nsaids, lidocaine patches, and only mild relief with vicodin. I am starting to do phsyioball and core exercises and have noticed that when I contract my glutes the pain is relieved. Sound familiar to anyone?
