What Causes Pain In Lower Back, Near To The Rib Cage?
Doesnt look like pinched nerve
Thank you for posting your query .
I have gone through your entire problem and I feel that its not pinched nerve , it is unlikely to have a nerve compression at the site you have mentioned . There is a possibility that it could be muscular pain or pleurisy pain. If it is responding then you just wait and watch . Rather then paracetamol you can try antiinflammatory like naproxen if there is no contraindication for the same .
It will help to heal whatever injury or muscle pull is there , but if the pain worsens we can evaluate further .
