I have pain in the rib area, on my left side. It feels like an ache all the time. I can discribe it as pressure too. The pressure won't allow me to get comfortable at anytime. I feel this pain when I go to sleep and it's still there when I awaken.When I put my arm down the pain is between my elbow and my shoulder, right at the rib area. The pain starts right under my breast into to rib area around the leftside if my back. It feels like something is growing there. When I drink fluids it seems to make the pain more intense on my leftside. I just push that area and massage it and strecth it, but it doesn't make it go away.
