Wow!!! What a day!
This is fantastic. I am so happy you have finally gotten seen.

I know it was a terribly long wait. It is great you have a neuro who sounds interested, thorough and caring! and the EMG! Yeah! Damage at the fibular head seems the most likely. I hope they find something they can treat or think will improve.
All that and a block is coming? you're getting somewhere!
BTW, I can wear a sock and shoe and my PM and neuro still think CRPS. They say I have the hyperthesia instead of allodynia. Another PM thought no CRPS since the sock and shoe. So much splitting hairs...fair to say you got jacked up nerve syndrome.
Keep us posted! I am sending hugs for post-EMG.
