Hes still young enough to start again and hes trade is not that bad. I worked in engineering heavy work untill I was in my 40s batteld through the pain Had to stop in the end. I would suggest he needs stronger pain killers for a start Im on Humira been on 5months thats loosend me up but hasent helped with the pain but Im severe and have Kyphosis. For the pain I take Max strength Co-codamol and Tramadol together also use a tens machine for different joints this gives me relife. He must keep moving fishing and riding hes bike when he can will help a lot. But Ithink he must also not go into himself mix with people and relax with people other than you once he gets into shutting himself away it will be very difficult to get him out of it.He can always PM me if he feels he wants to talk to some one who understands.
