Hi Court, Please don't feel you are posting too much. It's normal to have tons of question and he makes us feel good to provide support and relate our experiences that may help you understand what is happening to you.
I read on RSDSA our water for therapy, swimming, etc should be 86 degrees and hot do ICE or don't get in HOT water like hot tub temp.
Red dots are common to RSD patients. I have them and during a flare, they are lesions which can be infected. They hurt and sometimes they itch. It's hard to look at, but photos on the board show all kinds of skin problems.
This is an autonomic disorder, which means involuntary organs affected. Circulation, high and low blood pressure, skin rashes-red dots. immune system is compromised. short term memory loss, grasping for words while talking, not remembering the words.
Read as much as you can. I like RSDSA web site and rsdrx.com especially under puzzles. puzzles is a list of 146 questions with Dr. Hooshmand answers. He is retired not, but his website has a wealth of information. Another Dr. in Florida has taken many of his patients.
Hope you continue to research and stretch, move, heat healthy. Remember some meds cause weight gain and try your best to not let that happen.
Do you have a good RSD Dr. with experience? Take care of yourself, loretta with soft hugs
