For two months now I have had a persistent pain and discomfort in my right flank area. It hurts in my lower right back and wraps aroung the bottom of my rib cage to the front right side. It feels like a vice grip around my lower rib cage in front, or like a belt tightening. Also, when I sit, particularly while driving a car, it feels like something at the bottom of my ribs is pushing back. I had CT scans, urinalysis, blood tests, and finally an MRI with contrast. all showed nothing! My doctor sent me to an Orthopedic doctor who thinks it is nerve pain. Possibly from shingles, but I had no rash at all. Doctor put me on Lyrica, but it didn't help at all. My doctor is stumped. The pain is driving me crazy. It interferes with everyday activities. What could this be. Anybody else experiencing such a wierd pain? Any help would be appreciated.
