for almost two weeks now, i've been finding blood in my nasal mucous
during intermittent allergic bouts throughout the day.  over the last
couple of days, ive felt very mild to moderate pressure on the sides of
my nose bridge, in between the eyes--and when the pressure builds up,
there's also often blood in the mucous.  there appears to be no nasal
infection, as the mucuos is white.

went to an ENT last week and got a screening CT of my paranasal
sinuses.  the radiologist's impression (and concurred by the ENT) were:
1) right maxillary retention cyst vs pulp, 2) ethmoid sinusitis, 3)
mild rightward nasal septal deviation, 4) patent ostiometal units, and
5) congested inferior nasal turbinates with glandular mucosa.

the ENT ruled out any cancer and said the maxillary cyst was not the
cause of the bleeding, and was nothing to be overly concerned about.
he prescribed xyzal (an antihistamine) for the allergies.  he did not
elaborate on a definite cause of the bleeding, just saying it was due
to my thin nasal membranes and aggravated by the allergies.

not really satisfied with the 'indefinite' explanation, i've been
reading up on sinus literature over the web, including posts in this
group.  since the ENT visit, the allergies have been alleviated to a
degree, but i still do have blood in the nasal mucous.   im thinking of
getting a second opinion        with anothe ENT.  what could be the
cause of the bleeding?  i think the bleeding may be in the ethmoid
sinuses.  what could i be taking aside from antihistamines?  for the
etmoid sinusitis?  

thanks in advance for your inputs.
