Hi Thanks for writing 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). The pinched nerve leads to numbness, tingling sensation and weakness of leg depending on severity of compression. In the follow up query I would like to know are you able to walk on your heels and toes? That will give me some idea of severity of nerve compression.MRI of spine is the preferred investigation. following management- 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. The medicine given is tab.pregablin,tab.thiospas A8,Gel.flexabenz for application at back and oral/inject able form of vitamin B12. 4. Physiotherapy also helps. These are prescription only medicine so you may talk to your local doctor. Contact immediately to the emergency room (ER) if the weakness in right leg increases along with loss of bladder and bowel control. Take care and I shall be glad to answer any further query.
