Hi can i please be advised on a lower back pain on my left for the past 5 days and when im sitting down it goes away then comes back when standing or walking ?

Low back pain: This can be due to paraspinal muscle strain or inflammation of the sacroiliac joint. Try alternating cold and heat applications for 20 minutes every few hours. It's best not to stay in bed when resting your back,but move around as to!erated. Anti-inflammatory medications like ibuprofen or naproxen should be tried. Your MD may be willing to order a muscle relaxant to relieve tightness or see him/he

Some causes: Unlikely to be a disc issue, but as mentioned, consider sacroiliac, but also facet arthropathy, piriformis syndrome, lumbosacral muscular strains. If SI joint, can get relief from a sacroiliac belt, which should be available in drug stores.
