Damn that’s a pretty fucked situation and totally understand the nhs and GP’s being useless in recommending sports physios.
My old physio (ex premier league football physio) said to me that doctors will alway say rest and pain killers before further treatment, by that time it could make it worse .
I’ve told mates not to bother with a GP because that’s always what happens and go straight to a physio instead , it’s worth the £45 to get it looked at there and then.
