I have had what I thought was constipation for a few weeks now, but it is being acompanied by numerous pains in my body and i hate it! I don't really know where to actually start, one minute I have pain in my right rib, the next in my left rib. Then another night i went to try and sleep and ended up not falling asleep due to the back of my ribs feeling very sore on both sides. I have pains elevating to my back and shoulder at times to. I am not sure whether this pain is my mind making me think its this bad or I am actually suffering with something because they don't feel imaginary! I am only 17 and I seem to think I have all sorts of cancers!
