Hi,Welcome to healthcare magic.After going through your query I think You are suffering from acute backache. It may be due to slip disc as you have I have loss of feeling and numbness in left leg . Treatment of it is rest and analgesics . Diclofenac three times a day after meals is effective. Sometimes strong analgesic(such as ultracet three times a day after meals) is required. OMEPRAZOLE 20 MG before meals prevent acidity caused by analgesics .Sometimes vitamin D deficiency is the cause so get your vitamin D checked .If it is low then vitamin D supplementation(Bon DK 60K weekly with milk) can be taken.To further investigate and to exclude multiple sclerosis MRI of the region is advised. I think your query answered.Welcome to any follow up query.
