<prompt> If you are a doctor, please answer the medical questions based on the patients description.I been having occasionally deep throbbing pains in my lower back, so bad that it makes me feel like Im in labor had a hysterectomy so Im not pregnant. Could this be kidney related or musle related pain? I do have degenerative disc do to getting hit by a car years ago...could this be related as well? Please help...I tend to get this pain when Im sitting or laying down.  <response>: Hello, Welcome at Chat Doctor. I have read complete details of your question. It looks from your details that you are having pain in back which increases on sitting. Such type of pain can be most probably due to disc problems in spine or due to arthropathy or joint problem at spine. If you are over weight then this can also be one of the reason for that. Muscle weakness aggravate this problem. Pain due to kidney problem radiate from back to groin. There may be associated burning during urination or blood in urine. At present you should do following to have relief in this- -Avoid lifting heavy weight. -Start doing exercises as described in following web link- -Do warm fomentation over the back with red rubber bottle which is available OTC. This will give muscle relaxation. -Take a mild analgesic like paracetamol. -Have complete investigation including x-ray of affected part to rule out any problem. The MRI will be best for this. Hope this all will help you. With best wishes.
