For past week I had some minor chest pain just like a point not continuous and not in the entire chest. I visited a doctor and my BP was 150/90, he said if while walking it's not paining then it can be due to acidity and he gave me some medicines. It's been a week now there is no pain as such but my mind is always thinking about it that it's paining and sometimes I feel pin like pain. Now while I sleep my heart beat is bit fast which is worrying me. I do not have any problem while walking, climbing stairs, nor shortness of breath. Please suggest what to do.
