Hi Minnie,

Welcome! I am sorry for your reason for being here. I hope the forum helps you find some answers and community. Very odd with your symptoms, sounds so much like a disc/nerve root issue for sure! I don't know that MRI or any imaging for that matter is ALWAYS the bomb. There is interpreter skill involved and non-florid radiographic findings don't stand out to every interpreter. If you see neuro or neurosurgery take a disk of your imaging with you. I would call and really stress the urgency and acute change. If there is nerve compression in your neck that can be an urgent situation and they should have work in appointments for such a case. Also you might consider trying to get in with a Physical Medicine & Rehabilitation doc if neuro can't see you. PMR should be familiar with nerve/musculoskeletal issues and may be able/willing to order a nerve conduction to see what is getting through your poor arm. If it's CRPS it's CRPS but any treatable cause has got to be ruled out.

Hang in there! Sending Healing Love , Littlepaw
