it takes time to get to know how to understand and manage your rsd pain. be patient with yourself and take it a day at a time because each day with rsd is different so you won't know what you can do each day until it gets here. i learned that overdoing it on a day that i'm having a low pain day isn't always good because i pay for it with horrible flares for days after. so i try to pace myself even on low pain days as well as high pain days. in time you will learn how to avoid flares to a certain extent. sometimes flares happen even when you don't overdue it. weather can cause flares, rsd spread can cause flares and getting other diseases due to our weakened immune systems from rsd can cause flares too i.e. fibromyalgia, arthritis, osteoperosis. when flares happen that are out of your control. continue taking the pain meds your dr prescribe and have an emergency rsd flare kit. mine includes heating pad or blanket, lavendar epsom salt baths, tea, cookies, a comedy on tv for distraction while i lie down to rest until the flare passes.
p.s. i have had rsd for almost five years now and though i have learned alot on how to manage my rsd pain i am still learning every day how to deal with it due to spread i am getting from it. i just keep taking it a day at a time. soft hugs.
