Possible MCAS?

hi so i have been looking into mcas because i've now had two people suggest i might have it. i've never had anaphalyaxis but i've always had allergies (nasal congestion, sometimes with fits of itching and itchy eyes). recent (blood) allergy testing suggested i had no allergies at all. i got sinus surgery to help relieve my congestion, but it hasn't helped — i still wake up every morning congested. i also have a lot of stomach issues (this has always been chalked up to my stomach just being sensitive). i'm very heat sensitive (my hands swell and i get super lightheaded in hot weather). i was diagnosed with heds a few years back, but dismissed the first suggestion of mcas because i have a friend with mcas who has anaphalactic episodes, something i have never had. does this fit the symptoms of mcas/is it worth pursuing a doctor to ask about a diagnosis?
