Hi I have been training for my first 1/2 marathon and I know that I will be sore etc after a run. But I have noticed I seem to be taking longer to recover. I have had lower back pain for the last 18 months I have had x-rays and a Ct scan  and nothing showed. I am taking a 24 tab box of nurofen a week and also rubbing voltaren gel on my sore parts.Not to sure what to do?
Hello, Welcome at Chat Doctor. I have read your query. It looks that you are having back pain since long time. There are various reasons for such chronic or long time back pain--Degenerative disc disease, where there is age related changes in disc & it becomes decreases in size & resiliency.-Prolapsed disc between the vertebrae of spine.-Arthritis of joints between the vertebrae which forms the backbone.-Abnormal posture.-Chronic muscle strain due to working in odd conditions.-Lumber spondylosis(This is a degenerative disease of spine)& various others. By looking at your details I shall advise you to consult to an orthopedic doctor. You should ask for complete investigation including complete blood examination & an MRI of spine to rule out the disease. At present with mild analgesic like Advil, you may take the help of a good physiotherapist. This will give you relief. Hope this all will help you. With best wishes.
