Your mouth "filled with blood"? Whoah. Assuming that this is related to the Flonase is exactly that -- an assumption. This should be taken seriously and examined.
Hi,
Can you please tell us is it only the sinusitis that you are having or allergic symptoms (frequent sneezing, running nose and nasal block) also associated with it.
If you are having nasal allergy associated I would advise to visit your ENT specialist for a thorough examination and change in the medications if it warrants.
If you do not have any allergic symptoms then stop the nasal spray, use saline nasal drops, oral decongestants (such as Sudafed) for few days. If you have any thick discharge coming from the nose also try taking mucolytics (ambroxyl/bromhexine) if not, this is not necessary. Remember, drink plenty of warm water.
If bleeding persists, please do consult your doctor at the earliest.

There are a lot of steroid nasal sprays that you might react better too. Nose bleeds are a common side effect so a different brand may help better. Others are ayamys, nasacort, or nasonex, plus many others.
Nasal rinsing using a neti pot or neil med sinus rinse may also help flush out anything that is in your sinuses and there is a much lower risk of bleeding since there is no medication, it's just pure saline.
