Thanks for writing to us.
I have read your query in detail. The symptoms you have described are more likely to be symptoms of muscles strain.
To get relief from the pain and for quick healing:
1. Do hot fomatation at the site.
2. Apply local anti-inflammatory gel 2-3 times a day.
3. Take anti-inflammatory drugs like Ibuprofen
to reduce pain and local swelling or inflammation.
4. Do not lift weight on head or back or try to do exercise that involve painful muscles.
Wishing you good health...
