HI Desi, it is terrifying. I have been through stages of everything you are saying and have searched the symptoms pages in the early years of this and I too had them all just about. I dont go there anymore as it is always in the end the rsd. It alone is so horrible. try not to torture yourself. Dont overdo like the bike ride it will cause major flare ups later, a few hours later. Gentle exercise Ok. take care, CZ
