Your pain sounds just like my mom's! She had it in her hip where her psyatic nerve is. I laid on my mom's psyatic nerve for the last month she was pregnant with me. The doctor said she'd always have problems with her hip because of me (I was a real pain in the butt, hehe, ok corny, I know). She took a half of a Lorazapan (a muscle relaxer) every day for the past few days. It has gotten better but she was lifting some stuff in our attic for Christmas decorations. She says it's probably due to the lifting and the cold, damp weather that's hung over our area for the past week or so.

She also sat on a heating pad for most of the time because it hurt so bad she could hardly stand up.
