I posted last month about a stabbing pain under my ribs and general ache in my back and right side. I have since had a period for 1.5 days instead of my normal 6 days. I had severe pain in my lower pelvic region and could not walk for two days. My right thigh also ached. All symptoms then dissapeared for a week until they began again like clock-work 4 weeks to the day that they originally began. It seems to be worse when I am sitting for long periods of time or when I lift heavy objects. I have had x-rays and CT scans and I am just waiting for the results. Does any one have simular experiences?
