A ruptured an Achilles tendon and it took me a year to heal with special shoes.
It was your typical shopping cart accident. Tendons are slow to heal but surgury speeds things up.

Get well soon Steve what ever its called.

I have the same pain that an amputee would call phantom limb pain from a severed deep sensory nerve.
It is exaccerbated by neuropathy. Perhaps it constantly triggers my own endorphins so it comes and goes. It is minor compared to migrain which I outlasted 10 years ago. Lidocaine works in a pinch but...

'Endorphins are forever.
They are all I need to please me
They can stimulate and tease me
They won't leave in the night
I've no fear that they might desert me'
