A week ago I was sitting on the floor drilling a hole horizontally. I was really pushing on the drill with my chest when I heard a pop and felt a sharp pain in my right kidney area. I assumed a pulled muscle or ligament etc. The pain got progressively worse as the days went on. The 3rd day I was nauseous and experiencing dull kidney pain. I'm still assuming a pulled muscle. A week later and pain still in the area as if I was kicked in the kidney. Could I have done any kidney damage when I pulled the muscle or are the symptoms just the same?
