Hello,Thanks for your query.After going through your query I came to know that you are probably suffering from lumbar disc prolapse. It can be confirmed by MRI scan.treatment is rest in position of relief(generally lateral position with both knee bend),neurotopics such as mecobalamin and analgesics .As analgesic causes acidity,aceclofenac can be taken as it causes less acidity. Omeperazole before meals prevent acidity caused by analgesics .You should avoid bike till you recover. You can discuss with your treating Doctor about it.I do hope that you have found something helpful and I will be glad to answer any further query. Take care.
