I noticed some bumps on the back of my shoulders yesterday, it felt like a rash. Didn't think much of it.
This morning I felt a rush of stinging sensation across the area - the whole width of my back, just the top three inches or so. It lasted about 10 seconds, sort of sparkling all over the place rather than constant, and was surprisingly painful.
I had it again a second time, as far as I remember it was when I was picking at a scab on my leg which was painful (I think this is relevant!). I asked DH to have a look and he said it was bumpy but not red or anything.
I've had it again twice more, so four (or maybe five? I can't really remember) times in total today; the most recent was when I was injecting my diabetes medication into my stomach. It felt as if maybe it was related, like when I was picking at the scab; as if it's some sort of nervous system issue.
Has anyone experienced anything like this before?
