Over the years I have had episodes that involve intense/extreme pain, sometimes felt like squeezing across the top of my back. I all of a sudden sweat profusely (cold sweat), I have nausea and headache and the colour drains from my face. I feel so unwell. The pain will wear off, sometimes it can last for a couple of hours or more. It leaves me sore across my back with muzzy headaches that just won't go. I feel generally unwell with a muzzy head before it happens. I've been up to the hospital with this when it happens and it may not happen for months/years at a time but it has never been explained. I was diagnosed with Fibromyalgia a few years back and this time that I had one of these episodes they said it was a Fibromyalgia flare-up.
Has anyone else experienced this?
