Yes, my skin burns randomly everywhere! I believe it is our overactive nervous system. I also get red and itchy. Many people have been asking questions like this, which I find interesting. I never realized these symptoms are so common! I never had any of this ( everything else though) in my 30 years of fibro. My naturopath believes it could have to do with covid. I brushed off that theory until I researched it......makes you wonder.

Ugh! Me too...but not the stomach. It's ALWAYS the sole of my left foot. It itches soooooooo bad. Mostly I put hydrocortisone cream mixed with Homemade Arnica salve with socks on both feet EVERY NIGHT! It's the only thing that works for me.

I too suffer from Fibro faux sunburn.
Toes, thighs, back of my hands but more often it’s my arms.
I think it’s also coz I notice it more on my arms when I move the clothes I have on trigger the pain. I moisturise and take nurophen for inflammation. It tend to ease it. I think being a little dehydrated can increase it too as I’m not a big water drinker. But I try to drink it as often as I remember as it helps with this and keeps my headaches to a dull roar than a freight train.

Dose anyone have burning skin also in their toes and fingers?

I get this a lot especially on my arms
