could be one possibility. Have you tried breathing and relaxation exercises? If no, I would suggest you try it. Also try applying volini
gel on the back and 15 minutes later apply hot fomentation. Has an MRI
of the back been done? You haven't mentioned if you are male/ female. I would suggest a urologist
opinion if you are male or a gynaecologist opinion if a female to rule out more sinister causes of backacke.
Hope this helps.
