The left side of my lower back,right above my hip, is numb,and it pains and tingles constantly?

Musculoskeletal pain: If you are active (weight lifting, sports, etc), it's likely simple low back strain - very common. If you are not having any weakness in the legs, trouble moving your bowels or urinating, and no fevers (the "red flag symptoms"), you can give it a few days to see if it resolves with some rest, gentle forward bends and perhaps some ibuprofen:600 mg every 6 hrs. If any red flag symptoms, see a doctor
