What can cause a sharp pain on the right side of my stomach and a sharp pain on the same time every time i move?

It depends!: How long have you had this? Did you injure or do some unusual activity? Do you have any other symptoms, like fever, change in bowel habits, change in urination? Hard to say for sure, but often pain that only hurts with movement is often due to an injury to a muscle, or joint. If you have had the pain for more than a few days, it is worth getting checked to find out what is going on for sure.
