Welcome to HCM
After going through your problem which is going on for last 7 days,it may be related to stomach and reflux of acid in the food pipe (Oesophagus) ,but as it is not relieved so far hence all such discomforts are not related to stomach or acid.
Many times such complaints turns out be cardiac in nature,so you should not ignore it and get your self examined by a Physician and if requred necessary investigations to know the cause of your discomfort.
If it is cardiac or non cardiac cause like muscle or lung problem.
ECG,X-Ray chest,and/or Endoscopy
of upper GIT may be of great help in your case
Good Luck to you .
