If the guy you are talking about is Brian Simpson in Ipswich then my bruv-in-law recommends him highly - he was OK to race only two weeks after breaking his collarbone in two places at Brands a couple of months ago after two sessions on the same day at £60 a time (except his bike died in practice). But isn't he mainly about sorting broken bones rather than muscle/tissue injury?
Anyway, the website is
