Hi John

Thank you very much for the reply. I really appreciate you finding some information for me. I actually did find something very useful on that site. Something called Neuromuscular ultrasound being a way to diagnose my son.

My son was due to go back to the Neuro during the lockdown..but we still have not taken him. But my husband will be messaging him , as we can ask him his thoughts around femoral neuropathy (based on the website you sent)

Thanking you once again
