My Husband Is A Type 2 Diabetic On An Omni

My husband is a Type 2 diabetic on an omni pod. He also takes Pradaxa for AFIB. Since the middle of last week he has been experiencing extreme pain that starts in his right shoulder and radiates down his arm to elbow and hand. The tip of his thumb and forefinger also are numb. Does not seem to be the same symptoms as the frozen shoulder he had in his left arm. Heat relieves the pain somewhat but because of his other meds, he only takes Tylenol. Trying to determine if we need to go to neurologist or orthopedic doctor. My email address is YYYY@YYYY . Thank you!
