You need proper clinical examination and investigations.
Investigations include routine hemogram,RBS,RFT,LFT,Ultrasound

First you should take analgesics with muscle relaxants for 3-4 days.
If it is musculoskeletal in origin,it will subside with these medicines.
If condition doesn't improve then you should consult your surgeon.
