Dear doctor i have pain on my shoulder while lifting it since last month i used anti flamation but with no result?

Protect the shoulder: you might be having more than inflammation you might having some tear in the ligament that protect the shoulder we called them rotater cuff my advise see your doctor you might need MRI to your shoulder to check the stability of your shoulder and the status of your muscle and ligament thank you and good luck

Need more test: Various mechanisms can result in shoulder pain, including: musculoskeletal (muscle sprain, ligament strain, impingement syndrome, shoulder separation, myocardial trigger points, osteoarthritis, rotator cuff injury, SLAP labrum tear), neurological (cervical radiculitis, peripheral neuropathy), vascular (thoracic outlet syndrome) or referral pain from visceral organs. Exam by your doctor is a start
