Usually I get this problem:While driving my scooter,wearing a mask,deep thinking (I am overthinker and get tensed easily), while sitting idle. However there isn't any chest or abdomen pain. This intense few months back, now reduced after having ayurvedic treatment.This problem started when the first lockdown started.I have small umbilical hernia and fatty liver.A doctor said that I get panic attacks.
