If you have recurrent episodes of severe pain or pain that restricts your lifestyle then you should also focus on physiotherapy (once the current crisis subsides ) and postural care.
I would not recommend taking aceclofenac for long, specially if you have gastritis or
diabetes or
kidney dysfunction.
Just tide over the current crisis and try and manage yourself with OTC analgesics and physiotherapy and postural care.
Next Steps
Repeated attacks may warrant repeat MRI and further management.
