Sorry ValentineBaby -
I'm not sure what the answer to your question is. It is horrible. I have been traveling and experience this kind of flare while trying to sleep. I feel like I've stuck my finger in an electrical outlet.
But I do know that it is a common symptom and also occurs with a herx from tx.
I posted about
it as well - there were good responses and suggestions. I still haven't nailed down the source but it seems to be either chemically-induced due to the hotel sheet, cleaning chemicals? Maybe airborne from the conditioned air?
