Hi. Several weeks ago I woke up with pain in my side, below my rib cage, along with a swelling sensation in throat. Two weeks ago the pain peaked, at which point I started taking Nexium. I consulted a doctor and had blood and urine tests that came back negative. The pain in my side went away. However, a back problem that has persisted for nearly a year flared up, a pain that is in close proximity to the side pain and which worsens when I do things like cook. Today I started prednisone, which in the past alleviated the back problem. However, I am experiencing a lot of pain now in my side, under right rib cage, a sort of clenching feeling with some sharp pain. Any ideas of what s going on? Thanks.
