So I'm just seeking input from others because I'm not 100 sure. Basically I've had tingling in my left hand since mid-December which came out of nowhere and concerned me, especially as my family has a history of brain conditions. I went to a GP who tested my reactions, grip, etc. and said that he didnt see anything to cause concern. Since then, the tingling has stopped but the area of my arm towards the wrist still feels "weird".

I'm not sure if it's a genuine problem or if it's in my head, as I went through a period between Christmas and New Years where I stopped thinking about it and I didn't notice anything.

I'm now pretty obsessed with this and have noticed that my heart appears to race pretty fast whenever i think about it.

Has anyone experienced anything similar, and how did you deal with it? Finding it difficult to not fear the worst.
