This is Dr. David
were you drinking alcohol before?
do you have excessive anxiety symptoms?
excessive anxiety can cause you to have high blood pressure and high heart rate
dehydration can cause fast heart rate
high thyroid hormones can cause high heart rate.
no, I haven't been out to dubai.
did you get your thyroid levels checked?
more likely you are fighting a viral infection
viral infection can cause eyes blood shot, high blood pressure, heart rate, pain in your arms and legs, and pins and needles
have you been partying too much?
not getting enough sleep?
I would stop drinking alcohol and drink water and eat more fruits and vegetables.
you may be low in electrolyes and potassium and magnesium in your system.
I don't think your symptoms have to do with the flights you have taken
