<s>[INST] Dear Dr., I have severe back and leg pain for six weeks. I got 3 cortasone injections, the last one on Friday10/9/15. They did not help, the pain is not subsiding. I am taking 3 meds for 6 weeks. Diclofenac, Cyclobenzaprine HCI and Oxycodone. I am using Tens unit also. Today Tuesday 10/13/15 I have burning pain in my back and groin. Do you have any advice for me please. Sincerely, George [/INST] WELCOME TO Chat Doctor! Thanks for the consult on world's best portal for online help. I can realize the health concerns you have and will help you today for the same. Well, it seems to be an issue with the intervertebral disc in the lower lumbar region. When there is a disc herniation(dislocation) or bulge, it causes the misalignment of the vertebral column. There are nerves that are coming out of the vertebrae which get disturbed by being pinched in between the two vertebrae. This causes severe pain that is all what you are having. Painkillers can only temporarily help you to relieve the symptoms. For a definitive treatment go to an Orthopedist who will go for complete evaluation and an MRI will tell what actually is going on in there. Treatment then goes according to the cause. Hope I answered all the queries you had today. If you need further assistance, feel free to consult me anytime. Regards! </s>
