I've been having a bit of trouble with my Pelvic S.I. joint for a few days. Today the pain was enough for me to visit my Chiropractor (who just happens to be an archer). Anyway ... after a very painful S.I. manipulaton and a muscle massage ... things are sore but much improved. However Ian (my Chiro) told me .....no archery for two weeks ... thanks Ian .. you're a real pal.
