Hi Sandel,
I am prone to cysts, ulcers and rashes and My Pain team explain them as a result of the dystophic changes caused by RSD/CRPS.
I believe that the increased sweating we often have can cause our pores to clog up which would increase the chance of bacterial infections and then the cysts etc.
Just an idea
Does seem to make sense in my case.
Cheers
Tayla
