Hi Jackass123456789, This information is what I remember from the consultant and physio, a bit long-winded, but:-
My dislocation was posterior [backward], and trapped the nerves/ligaments that operate fingers. Appartently the longer you leave the dislocation until it is put back in, the longer your arm takes to recover. Hence, forefinger and thumb, not working.
So, my idea of not calling the mountain rescue, was not a good one, especially when I later learned that they were training in the same area. Also, they said that they would like to rescue a living person for a change.
Anyhows, a 4 mile walk, then picked by wife in car, ended up in a 6 hour delay in reseting the shoulder.
The damage to nerves take approx 1mm per day to repair, and the length of your arm takes 18 months. Nicely, if you leave it too long it can stop ciculation in your arm and possibly result in amputation.
