Welcome to HCM
We understand your concerns
I went through your description and can clearly tell you that you are not having symptoms of heart attack
. Apart from what you mentioned, there are so many other symptoms for a normal heart attack. Also you are mentioning that you have acidity related issues.
You should know acidity. Acidity caused by indigestion
or excess secretion of digestive juices. Such acidity produces reflux and pushes the diaphragm up and we feel tightness and pain on the chest area. Sweat must have been caused from different cause and palpitation
happened due to anxiety
. You are just 31. Exercise and reduce the chances of diseases.
For now, you can consult a general physician and check your vitals and he will advice you to take EKG and if necessary STRESS TEST
. You had quit smoking and try not to restart smoking. Exercise regularly and eat balanced food. Include garlic and onion in diet daily.
Hope I am able to partially clarify your doubts. Available for further enquiries.
