Hi Dr. Rynne. i am seeking a 2nd opinion. about 4 months ago, as i was walking my beagle, my right arm got pulled very hard. i was not paying attention to the dog & he surprised me with a very strong lunge. my doctor was booked up so i saw his nurse. she sent me for x-rays. i received letter from office telling me x-rays were normal. Next step that Nurse Jean had me lined up for was MRI. She is no longer with this office. My Dr. wants to give me an injection. i have a feeling that this is the wrong move. The MRI would pinpoint the cause for the uncomfortable pain. What is your opinion?
