I have pain in my kidneys when walking longer distances (6 to 8 km). i am currently taking nitrofurantoin and ciprinol. can i keep walking?

Pain: How you know that the pain is related to your kidneys is the obvious question. If you have had kidney stones previously you need to be seen by a nephrologist or urologist and evaluated thoroughly. Hopefully you are not on chronic nitrofurantoin. This is a potentially quite dangerous medication, and if you have kidney infection it will do nothing for you. Ciprofloxacin may or may not be helpful.
