I have a very severe problem with my sinuses. Some days I sneeze all day using about 100 kleenex. Other days my nose runs continously.
I have been to an allergist,two ent doctors and had x-rays of my sinuses. All the doctors tell me that nothing is wrong. Does anyone else suffer from this problem?
A lot of CPAP users have the sneezing and sinuses problems. And there are so many things that could cause these problems, when you start using the CPAP machine.
That's why we need more information of what's going on, so we might be able to help. For example:
what kind of CPAP machine you use,
do you have an unheated or heated humidifier,
what kind of mask you have? A nasal mask, nasal pillows, or a full face mask?
are you a mouth breather?
do you have water in CPAP hose in the morning?
how do you clean you CPAP equipment?
One of the biggest reason you might be having a running nose is because the air is not moisturized. If you aren't using a heated humidifier, you might ask your doctor about getting one.
If your humidifier is not heated, a heated one may really help your sinuses. However, you have to find the humidity settings that works for you. Everyone is different.
What kind of doctors did you visit, except the ENT and allergist? I would call both my primary care physician and the sleep doctor's office. They will recommend what should you do next.
Your problem does sound like you're having some kind of an allergic reaction, but you said you don't have any allergic problem. But maybe you have allergies from the air that you breathe through your CPAP machine.
Unless you have a HEPA filter on your CPAP machine, and most of us don't, the pollen will not be filtered out. The CPAP filters only remove the big particles from the air.
While you have the sinus problems, a sinus rinse or irrigation is recommend. It should make you feel great and get rid of congestion.
