[|Human|] I have had a sharp and achy pain in my very low left back for the past three days. It radiates down my leg and makes it difficult to stand or walk. Now I discovered there is a splotchy, round, indented bruise in the area. It is very sensitive to touch. I dont remember any injury though! What could this be? What should I do?
[|AI|]  HiT hank you for asking ChatDoctorI have gone through your query. Your problem is most likely nerve compression pain. It can be due to sciatica or lumbar radiculopathy caused by nerve compression. A physical examination by orthopedic will give clue for that and an X-ray followed by MRI of lumbosacral spine might be necessary to confirm that. Analgesics, muscle relaxants and physiotherapy is usually advised for such patients and most of them are benefited also. If no improvement then a surgical decompression of nerve is advised. Hope this may help you. Let me know if you have any further query.
