pain in the shoulder radiating to the elbow with tingling
is matter of concern. you said already you have an MRI
checked by doctor, if you are not sure about the diagnosis you can check again by sending the scan report. your age and type of work reflects the signs and symptoms if it is mild you can go for physiotherapy
with prescribed analgesics. with no radiological changes i mean defect in MRI, i think you need not bother much with your problem, if it is obstructing your day to day activity than you are very much in need of detailed evaluation of your problem.
