a lot depends on how early treatment starts, my worst bout was my 1st one, mainly because i was terrified of telling anyone. ended up in hospital for 6 weeks off school for 6 months. i was put on the steroids, prednisilone iirc, a few side effects, but i've lived my life without it impeding me, was told i couldnt do anything strenuous etc, but i played football for over 10 years sat and sun league and done work involving heavy lifting. had to switch from lager to bitter because lager was to gassy and bloated me.
