So last night I was work typing away an e-mail when I felt a sudden head rush out of nowhere which within 2 seconds translated into my heart racing (no chest pain), and breathing difficulties which lasts 4-5 seconds.
This kinda tends to happen when I worry too much about health related issues. And it all started being more noticeable last week.
Anyone experiencing this? Went AE and been recommended blood tests and if these come back normal it may be that I need beta-blockers?
