I am 21 weeks pregnant. I recently started getting a sharp pain below my rib cage on my right side. I am a hairstylist and typically stand for long hours. I don t have the pain when I wake up, it usually starts when I m at work. The right side of my back will feel tight, and then it seems to radiate around to the front. It is only on the right side. It feels like a sharp pain,sometimes a burning sensation, almost like a pinched nerve. It will hurt until I go to bed. When I wake up, it is gone. It is very uncomfortable!! Any thoughts?
