Sudden pressure in temples with stuffy nose

[DesTheRocket]

I am trying to figure out what could be wrong with me. I have health anxiety but also have been diagnosed with a few conditions. First,ekg's show rbbb with left anterior fascicular block and I have also been diagnosed with having hypertension which I take meds for (Lisinopril, Propranolol and Hydrochlorot). Every once in a while, especially when I am talking or feeling a tad stressed I get a sudden pressure in my temples with a stuffy nose on the left side. I recently had an MRI which was pretty clear (for the most part) and a doppler scan of my carotid arteries which were clear. No MRA yet, but I am wondering if I am a time bomb waiting for a catastophy. I want to be healthy and have lost weight, I eat right everything but don't know what to do next. Please help.
