[/INST] Welcome to Chat Doctor .1. At this age with your history I would recommend yo to do some back pain exercises would help.  2. Suggest to lie on a flat bed and positional care. 3. A Link from NHS please try.http://www.nhs.uk/Livewell/Backpain/Pages/low-back-pain-exercises.aspx4. If there is no use then you have to get an x-ray lumbar spine AP/LAT.(you mean - to your friend.) Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you. </s>
