I have been suffering severe right flank/
kidney/back/right side pain with swinging fever for two years. Last July i was found to have a pelvic mass which was successfully treated as an in parient. I had approx 8 weeks where i felt back to my old self, since then i have had recurring symptoms as above, i am hospitilsed every few weeks, they get symptoms under control with medication, i have had mri scan, ultra scans, all normal.
