Hi for about 4 months now I have been experiencing anxiety in my chest coupled with very red eyes and a very feverish feeling in my head even tho my temperature is normal. That lasts 3-4 days followed by 1-2 days of complete exaustion. Up untill a month ago it only happened about once a month but I have now had it 3 weeks consecutive with 1-2 days respite in between. Any ideas what that could be? Am I dyin or what? Thank you in advance.
