Chronic Pain on Both Sides - Need Help!

I am trying to figure out a doctor to see and what I have. I have gone to the ER many times in pain and they give me muscle relaxers and tell me to rest. While there they usually give me Morphine which is the only thing to actually take away the pain. It feels like a muscle or nerve on my hip that makes it soooo painful to walk or move. I can't even go to the bathroom because it's too far. i have to just heal for weeks. Depending on how bad the pain in sometimes I throw up and pass out. It has always been on my right side but I fell and now feel the exact same thing on my left! I was in shock. How could something be on both sides unless it's a nerve right?? Currently in bed, peeing in a bucket, and on muscle relaxers. Trying not to go to the hospital. What on earth could this be??
