hi zinnia. i have never tried capsaicin cream but have been using voltaren gel as needed to help with the stinging burning aching stabbing pain i feel because of my rsd. my pm dr prescribes it along with gabapentin and a strong pain med. i take the meds on a daily basis but have been starting to use the voltaren gel almost every day now too since my rsd has spread some more. maybe your pm dr can prescribe some to you too. i hope you feel better soon. soft hugs my friend.
