Thanks for writing to the forum!
Repeated blowing can cause blood in the mucus. You must consult an ENT specialist to rule out polyps, foreign body, and sinusitis. There is a possibility that you have allergy. Common allergens are pollen, mold, dust, pet dander, synthetic fiber, cosmetics or drugs. You must get an allergy test done, either a skin test or RAST, to know what you are allergic to. Nasal fungal infections too should be ruled out.
Whenever you blow and your ear closes up do the valsalva maneuver (Done by taking a deep breath and blowing while pinching your nostrils and closing your mouth).
Hope this helps. Do let me know if there is any thing else and keep me posted. Take care!
Hi thanks for the reply... Yes, I'm trying to look for an ENT Specialist at our local area. It's not plenty in here. A friend just referred one. But I'm a bit worried and reluctant checking out, my friend has allergic rhinitis but I couldn't see a lot/any of similarities of symptoms from Allergic Rhinitis or Chronic Sinusitis to my condition.
The over production of mucus just concerns me alot, but itch and sneezes doesn't occur in my case. Hope I am not misleading my thoughts...
Really wanted to be more informative before getting a consultation. Living in a poor country and getting sick isn't easy. Many thanks again for all the help.
