Hi,
I know this is most likely anxiety, but I've been experiencing the above symptoms for the past couple of days. I'm worrying myself into thinking that it is something more sinister than just over stimulated muscles and nervous system from all the adrenaline as a result of anxiety. I'm trying to stay calm and be rational about it but in my current frame of mind I'm finding it really difficult! Has anyone else experienced this or can help me convince myself that I am being irrational?!
