Sorry to hear this Arc124

I see you posted a month or so ago now, how were you in the end? As you know no one can diagnose online but there are other reasons for tingles, anxiety is one (not minimising what you were feeling though, I hate it when people tell me about anxiety because not all symptoms are due to that), muscular strain in the arms and wrists can bring about these things. A few times I've had that and worried and then later remembered how I was over using my hand grip on a task earlier or something like that.

Hope you're ok. I have stroke fears too.
