Hello Mr. Sourabh, shoulder pain can be because of many reasons such as tendon inflammation, muscle tear, ligament injury, bursa inflammation, etc. These things cannot be seen on x-ray.
I would advise you to consult a Physiotherapist and get correct diagnosis and treatment
Next Steps
Visit a Physiotherapist as early as possible
Health Tips
Do not lift heavy weights with that arm until you meet a Physiotherapist.
