I had stabbing off and on side pain in urq for three months, sometimes in lrq and llq. also past 12+ hours, stabbing back pain in urq. whatcould itbe?

See professionals...: The described pain at RUQ leads to consider gall bladder stone, or kidney stone, or intermittent obstruction of ureter, or spinal nerve irritation. And the pain in rlq and llq in females leads to worry about the concern in pelvic organs. But for what you stated, it would be most reasonable to see, talk, and work with a professional to figure out what is the matter in you. Best luck...
