Stomach Problem, Nausea, Diarrhea, Blood In Nose, Anxiety. Had Zantac, Lexapro. Is It A Sinus Infection?
Welcome to XXXXXXX
You seems to be suffering with Rhinitis &/or Sinusitis with post nasal drip.
Blood can come out of nostril on blowing out, if mucus membrane is dry.
Post nasal drip occurs due to excessive secretion of mucus by nasal mucosa.
But mucus generally doesn't cause nausea, while blood can cause.
If blood is coming as post nasal drip, it requires urgent attention.
As you are not feeling nasal congestion, sinusitis might be causing it.
To confirm diagnosis, examination of nostrils and pharynx and some tests on the basis of examination may be required.
Following test may be required:-T & DLC, Eosinophil count, nasal endoscopy, biopsy and X-Ray &/or CT scan.
In my opinion, you require examination by an E.N.T.Specialist as early as possible.
Mean while you can take anti emetic, antibiotics and anti histaminic with consultation to your doctor.
If you have further query, please feel free to ask,
With good wishes,
