<human>: I have chronic back pain, S/P slip and fall x 2 occurances. (Pinched nerve, DDD, and second fall: hernation with tear of disk). Multiple facet injections, 13 epidural injections and 2 years ago last procedure of radio frequency. (All have worked for a time frame of 8 months to 1.5 years). Currently have chronic lumbar pain into bilateral gluteus muscles and right side radiates into thigh down to toes (on the worst case senerio, usually stops in mid thigh). Last 5-6 months numbness noted in left lower abdomen started as half dollar area now grapefruit size area. (Feels like lidocaine feeling after teeth filling). Last back procedure was Jan 2013 radio frequency. What could this be? Edema? Work as floor RN. Thanks!
<bot>: Welcome to Chat Doctor I have gone through your query and understand your concern. You can discuss with your doctor about it. You are having degenerative disc disease. Your abdominal numbness can be related to radio frequency ablation or compression by pressure by degenerative disc. You need to do MRI lumbar spine to see compression. Analgesic such as ibuprofen is helpful in neuralgic pains. Mecobalamine is helpful in recovery of damaged nerves. Hope your query get answered. If you have any clarification then don't hesitate to write to us. I will be happy to help you. Wishing you a good health. Take care.
