I have severe pain in my left lower pelvic area, not when sitting or lying down, standing and walking, worse when walking in the pool, I suspect it happens worse there because of the buoyancy, I have had a CAT scan to rule out kidney and bladder problems, I had an x-ray of my left hip and was told my hip was fine. It is so bad that at times I cannot walk and must sit right away. Other times I have no pain when walking but that is not often.
