It happend last Friday and seriously hurts. I've been doing some stretches to help relieve some of the pain. I start my new job Monday and I can barely walk. I'm having little spasms on my left side where it hurts and in my abdomen. Any suggestions on anything that will help? I don't like takin meds and have taken aspirin a couple times and have used my heating pad.
