Orthopedics Questions? Ask an Orthopedist for Answers ASAP
It sounds that you would benefit to see an orthopedic specialist. You MIGHT have a tear of part of the rotator cuff muscles ( supraspinatus muscle or tendon tear might coinside with your findings...) So I advise that you consult this specialist for further evaluation.
I hope that this information is helpful for you.If my answers have been helpful and to your satisfaction then please remember to leave positive feedback.Thank You and Best Regards,
