<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have a tingling pain more of an annoyance in my buttocks which will occasionally extend upwards into my lower back and down the backside of both of my thighs. It s extremely uncomfortable when I lay down, I cannot find a comfortable position to fall asleep. What is wrong with me?  <response>: Hi there. Thanks for your question. Pain in the buttocks radiating down your thigh can be a manifestation of pinching if a nerve in your spine. Usually at the lower level that is L5 S1. Since its affecting your routine, you should get an X-Ray of your spine followed by MRI if requireddepending in whats seen on X-ray and whether u have relief with pain meds. Depending on severity of pinch u will need pain meds, injection or surgery. Hope this helps you. All the best. Regards Chat Doctor.
