I was trying to fall asleep and saw the thread and raised red dot thoughts.
Just to think out loud; Tos, fybro, and CRPS/RSD have to do with nerve activity, as part of their syndroms.
One thing Dr Togut could share with us at support group is hypernerve activitey of TOS, Allodynia, and also hyper pain perception. So if you have TOS sending hyper pain signals, or CRPS sending hyper pain signals, could the nerve tips at the skin react?

But tos and part of Crps, is hyper nerve sensitivity, sensory nerve issues, even myofascial...where the nerve inserts into the muscle and they muscle tries to protect it, makes a slpint causing muscle spasms...

If ther is a disconnection between the say feet burning, and the brain getting the signals, of the pain, would we still feel the pain? Is that notunlike a SCS that is confusing the pain signal. It is used for TOS pain, it is used for CRPS pain.....MS, and many others.......

Then also, think about shingles.....isn;t that a sensory nerve activity? I do notice, I do not get shingles, but I do get the red dots, and I can follow them around a nerve patterns. Some do get scabs on them, some take a long time to heal.

So couldn't it be just like herpes voister (sp) fever blisters, shingles, causing nerve ending flares.....
So the red pimples are inflamed nerve tips reaction....
I find relief from lidocain patches.

Like I said, just thinking outloud...
Many tosers also have lumbar and other syndroms too,
One thing that some TOSers can tell you about when they battle it, if theirs is sensory real bad, a breeze blowing, "HURTS" and Terry Cloth towel,"HURTS"..
