<s>[INST] Hi doctor, Yesterday, I bent down to pick up a grocery bag, and suddenly I felt a sharp pain in the lower right region of my back. And ever since, I have had sharp pains in that area whenever I walk, bend over or if I place my weight over my right hip, and whenever I put pressure on my right leg whilst walking. It especially hurts when coming up those positions. When I am not moving, I have no pain. My mom thinks it is a pulled muscle, but it does not have an aching type of pain. The pain is more sharp and intense when moving. Please help. [/INST] Hello.
