Hello, Thanks for your query. After going through your symptoms, they are suggestive of sciatica along with low backache. The cause may be confirmed by physical examination, but most commonly it is due to slip disc that is prolapsed of intervertebral disc leading to nerve compression (pinched nerve). Other causes are sacroiliac joint dysfunction,piriformis syndrome and facet joint arthrits and so on. As MRI of spine is the preferred investigation, I would urge you to visit a nearby doctor who can order this investigation. Until then my advice to you are: 1. Bed rest, that is avoid unnecessary sitting and whenever possible take rest in lying down position. 2. No massage at back and you may take hot water fomentation to relax the muscle of back. 3. If the pain is severe, you should be started on pregablin, muscle relaxants along with topical antiinflammatory prepartations. Oral/injectable form of vitamin B12 will also benefit you. Discuss with your treating doctor. 4. Physiotherapy also helps I do hope that you have found something helpful and I will be glad to answer any further query. Take care
