Well here it is me who can be cynical!!
On fri night hand and arm went dead in bed and woke up sat morn with v stiff back
I went along To this Bowen thing and it was amazing... sat night no dead hand and arm.. the technique involved minor manipulation/ movement of body.. muscles.. she said arm problem was coming from my neck.. have been telling GP and consultant for months,.. about this loss of feeling .. no action was taken!!.this session seems to have done the trick
