2 days ago i slipped in the shower and landed on my lower back/buttock area. It is hard for me to do the simplest things like sitting up, getting out from bed, etc. i can still walk around, as long as I keep my back straight. My hips also seem to be in pain bcos when i sit up after laying down, it hurts. My dad is a doctor as well and he suspects it s a muscle sprain since it only hurts when i move and it doesnt hurt when he applied pressure to my lower back. Also, the area below my stomach seems to be affected as well. Any advice on how to cope?
