I have CRPS and have it in both legs and it has affected bowels and bladder. I know this is a nervous system mystery disease I’m told. Been home bound mostly can only lay for 5 years. This disease came after second back surgery which was an (I forgot name) but go in from stomach and put a cage in and hope it fuses. Mine didn’t fuse so back horrible too. Not being able to finish sentences cause forgetting words and memory loss happening a while but these headaches are intense and vision affected and my weird like just laughing at a picture not even funny or crying but don’t know why.
