I flare in the shower too. This has gone on basically since this started. The warm water combined with a dependent foot makes for a red lobster looking tootsie with a lot to say about it. Since ketamine I am able to shower at the gym right after getting out of the 82 degree pool but I don't push hot water. I have been afraid to try showering any other day. My trick is to take a bath with my CRPS foot resting on the edge of the tub out of the hot water.
