I have been complaining of a pain in my left side, just under my ribs for over a year. As I have COPD the doctors say my lungs don t go down that far and ignore me. One doctor ordered chest x-ray last April but nothing resulted from it. I now see a new doctor who ordered a full blood test. That came back with I m low in vitamin D and have high cholesterol. My iron and glucose level were both good. I was then sent for an ultra sound of the spleen area and abdomen. I saw on the screen a lump in the area of the pain. Could this be a cyst as I have clusters of cysts in both breasts, which is being followed up on.
In my opinion you are describing splenomegaly symptoms, this limb can be either a cyst or due to use of steroids Good Luck
