I have pain in lower left-hand, rear quadrant intensified with recent bone scan, what could be the problem?

Bone scan..: I am assuming that you had a tc-mdp nuclear medicine bone scan. The tracer itself should not affect your condition. It is excreted through the kidneys and has a physical half life of about 6 hours. Perhaps the position you were in during the scan aggravated your condition. See your doctor for a basic workup with history, physical, and possibly blood tests.
