Hello, I am having pain in my waist. The pain has been going on form 3 days not. I first noticed it in my right side around my waist and that went on for 2 days. Yesterday the pain was more in my left side. Now today the pain is on both sides and I am light headed while this is going on and is gradually getting worse. This evening it is almost unbearable to walk. When I am sitting it is not at bad but standing from a sitting position, I nearly have to walk in a sitting position cause it is extremely painful to stand and start walking.
