Thanks for writing in.
From your description, it looks like a pain of muscle origin involving a group of muscles.
are only pain killers, the addition of a muscle relaxant
would help more. I would suggest you apply an ointment containing a pain killer and muscle relaxant combination.
As you have expressed that certain movements when initiated, are painful, please consult a physiotherapist and take an opinion and if required he may advise you to meet an orthopedic surgeon for further investigation and treatment.
Hope this helps.
