Hello,
Thank you for your query at DoctorSpring.com
I understand your concern.
Can you give me mor detailed history- as to how did the pain start? Where exactly in the pain? What is the type of pain? Has it been induced by sports/ weight lifting?
Seeing that the doctor advised you Naproxen, it seems like you have triceps tendinitis. If that is indeed the case, then this pain can last up to a month if it's severe. Sometimes when the drug therapy becomes refractory, the patients are advised physiotherapy and mild stretching exercises.
Has there been no improvement at all? How is the range of motion?
Feel free to discuss further,
Regards.
