Well, Georgie, your post explains everything. Madam T worked in HMP as an independent counsellor attached to NHS regime therein. I use the word “regime” intentionally – the whole NHS outfit was a bunch of squabbling, power-crazed nurses and doctors who were dumped into the prison service because they were no damn good working with/for the mark 1 general public. So bloody obsessed with power-struggling internal politics that needs of inmates regularly overlooked, much harm done.
Reckon that Pain Clinic might be best bet. That said, I suspect only way to get referral is to pay for a consultation with private doc.
