Strong pain in back(right above hip on right side) when i bend to touch toe. i dont feel this pain while running or doing anything else. exercise dail?

Back pain: Have you done any recent strenuous work/exercise/heavy lifting? It is most likely that this is a muscle strain if you have. In most cases, Ibuprofen/Advil (if safe for you to take) and cool compresses help to relieve the pain. If you don't find relief, it may be wise to see a doctor to further evaluate this. Another possibility could be a herniated disc. Best wishes.
