Welcome to the forum. Anxiety
can present in various ways and cause many symptoms. Since you have not been examined clinically since a long time, do not go by assumptions, get a medical check up done to assess your fitness.
Pain and tightness around the chest is not a good symptom, it can be due to some gastric problem, heart problem, tiredness
, stress, anxiety, depression
, sedentary lifestyle, etc.
I suggest you to get clinically examined before popping in any kind of medicine. Some antacids can give you temporary relief. If you are found fit clinically, see a counselor or a psychiatrist
. Take home made nutritious diet, exercise regularly and sleep well. Take care.
