Jeez Don - That is one Horrendous Story ! And I thought I had a dodgy trip after a motorbike crash ! I partially severed the nerve in my upper arm and had nineteen fractures and dislocations in my left wrist ! Minimal movement in the hand when they took the plaster off !
I had to relearn from scratch too - But I made up for it by learning barre chords the second time round . IF I hadnt had good medical support (AND the incentive of a nice Martin guitar) I sure as hell wouldn't be gigging now !
