Hi Honey,
I want you to know I care. My RSD came from a injury as well. It came from a fall 5 years ago. If I would of known I had severe nerve damage at the first year my nerves would of healed sooner.
Their is a test called a Neurography. It shows weather the main nerves are damaged or entraped. A reg. MRI will not show it. It will also show if something Vascular is going on. My subclavicle artery was very compressed.

Filler MD is my surgeon. Please email him and give your medical history. He has a heart of gold and is a nerve detective. He saved my right upper limb.
I know your young and this DX is so rough please hang in their. It will get better. I beg of you. Big Hugs, Roz
