I have pain in the right side of my waist all the time for the past 4 months sometimes in the left and right sides ,i throw up alot some weeks,I have had ultra sound and mri and colonscopy, upper gi everthing has came back negative, the pain is getting worse the doctors are having us write down everything that i eat, what could be wrong Thanks mckay

It sounds like it could be kidney/and or gaul stones...Or an infection. Your doctor should be able to check for these things without doing another gastro/colon-oscopy.

It could be a number of things.
I think that Chiropractors that are into alternative medicine do a much better job at finding the root of many problems. You might want to find a good one in your area.

It could even be a pinched nerve.

being that they did an mri and the colonoscopy and ultra sound, is it possible you pulled a muscle in your abomen wall? because these muscles are ALWAYS on the move, and because it puts strain on them all the time when you walk, lay down, sit down, stand up, pretty much ANY movement, it can take a long time for it to get better.

good luck hon!
