Hello Vikalp.
The pain seems to be due to paraspinal muscle spasm on right side..
The occurrence of multiple episodes may be due to stretching or inflammation of nerves originating from the spinal cord level.
Next Steps
I will suggest you start with hot fomentation, take analgesic with muscle relaxant tablet, apply analgesic ointment over the site of pain. If possible, also start with physiotherapy including SWD, Local US..
Health Tips
Avoid sitting down, avoid heavy work, avoid Indian toilet, avoid forward bending for now..
