[/INST] Hi I am Chat Doctor. .  I don't think your medication is the reason for your back and shoulder pain. I think it is a kind of muscular spasm due to overusing, heavy lifting, bad sitting and sleeping postures.  For now I may recommend painkiller like Advil tab when needed, hot massages with topical gels, muscle relaxants and some B12 vitamin supplementation will be effective also physiotherapy and even yoga are very helpful. If pain persists I suggest some lab investigations, X-rays and MRI and visit your physicianPlease click THANK YOU and consider a 5-star rating with some positive feedback if the information was helpful.
