I dialyse 3times awk at local hospital here in UK, and am on transplant list. I have had a pain on left side under my ribs on and off for a couple of years, but ignored it. This morning it became quite sore when I move, seems like when I use stomache muscles, i e to sit up and to stand from sitting. I think it is related to my spleen and am concerned about my kidneys. Please do you have any anenswers?
