Hi, I suffer from very bad anxiety have for over 4 years On a daily basis.When i have these attacks I have vision changes,rapid heartbeat,burning in my chest,dizziness,forget fullness and dry mouth.I have about 10 attacks every 24 hrs. sometime the burning in my chest comes from my heart beating so fast against my chest wall and causes it to burn even hrs after the anxiety has calmed.nothing helps now its to the point where if i get upset angry or stressed i get the same burn but it happens on the left side of my chest only and i also get sore muscle like pains in my left arm and shoulder lasting only a minute or so. You are not alone.
