Hello
I understand your concern.
Palpitations,
numbness over face may be due to general anxiety/anaemia/
hyperthyroidism.
But before that I would like to know if you have done with some basic tests.
If I were your treating doctor,I recommend,
-Investigation like ECG,blood glucose,blood haemogram,thyroid tests.
Further management depends upon results of these tests.
-Destress yourself with yoga and
meditation.
-Have a balanced diet.Avoid alcohol,smoking and caffeinated drinks.
-Minimum 8 hours of sleep.
-Consultation with
psychiatrist will be needed.
for anti anxiety medications may be considered.
Hope this information helps you.
Feel free to ask any more doubt.
