R flank pain and back pain. moderate and comes and goes x 1 wk. no other sx. causes and treatment?

Not enough info!: There is not enough information to be able to answer your question. Does the pain hurt only with movement? Have you changed your exercise routine? Do over the counter pain relievers, in normal doses, help? If your pain persists, see a doc this week. If you have fever, numbness, tingling, weakness, or loss of control of bowel or bladder function, or black or bloody stools, go to an ER.
