Weird symptom or ???

Question

Just a few minutes ago I started to randomly feel the top of my head start to tingle and burn....like you know when you are bleaching your hair and it stays for to long ....yes just like that ..super weird is anyone else experiencing this or am I just weird? Im 9w6d baby#3 and never experienced this with my other kids

Answer

Mine does this when my blood pressure is low and my heart rate gets too high (or when my blood pressure was high and my heart rate was too low..) 
I can’t remember exactly but I was doing physical therapy for my knee, and felt this exact thing. The therapist checked the monitor and told me it was one of the two causing the sensation
