Lottie's questions have so much sense,can be diferent kind of dots, one that looks like allergy and are painful, and also the other kind just red little dots everywhere .
Well ,in my case I deal with both , the ones that hurts normally appears during my period before,during and after, hurts like hell when my clothes roses them.
The other kind are just red little dots, no pain more like born marks instead of being brown are red,I asked my dr and none of them see a reason for any at all,and didn't related to rsd according to them but, I'm sure they are, happens after rsd and every month ,if we remember rsd is a neurological conditions that for sure can created some reactions in those over active nerves, my rsd seems to be in my whole body not only foot and ankle as before.
I was instructed to take Benadryl for allergy and continue with gaboentin and my regular meds, also some medications can affect the skin with the sun exposure ,I'm sure we need to review those prescription slip we normally get every month to see if any drugs causes any kind of allergies to Sun or by itself.
Hope you feel better soon ,take care,from Jesika .
