may take 1-2 days to show its effect. If some cases it is noticed that pain increases in the first two days of administration than gradually decreases. So wait for at least 2 days and can take analgesic
and anti-inflammatory drugs to control your pain.
If their is no improvement in pain than a MRI
of spine can be performed and the herniation which is causing the most effect may be removed. Means surgery can be performed to reveals your symptoms. Consult your spine surgeon
for that. You may take help of you physiotherapist, do regular exercise advised by them.
Hope this will help you.
