No, a clean MRI, and clean EMG might be enough to dyignose me with complex regional pain syndrome 2
I had an appointment for my EMG on Thursday 27th Augustwith Colleen Zittel, MD. Yes, a medical doctor preforms a EMG.
She was able to inform us that everything looked “normal” asides from my weakness in my left side, that is affected by the injury to my right brain stem that the car accident caused.

Dr. Zittel agreed with Dr. Mamun: CRPS2, but Dr. Mamun has to diagnose me, the soonest I could get an appointment was October 1st!!
I sent him the following message

If he doesn’t respond by tomorrow ma will call, I have a pretty severe speech impediment, so she’s my voice. Love that lady.
