Fell down carpeted stairs where my bottom took each steps impact as I went down. Still holding a full laundry basket under my left arm during all of this too...I stayed down to gather myself for a moment. After standing, both hips & lower back are all extremely sore and tingly. My lower abdomen feels full/crampy (without pms). Very uncomfortable to walk & lay on back. Tingling pain shoots down one leg to foot. Is this just bruising? or should I get checked tomorrow if not any better with rest?
