Hello,
What you are having can be due to sinus congestion especially chronic sinusitis. It can be due to allergic nasal polyps or tumors, allergic reactions, deviated nasal septum, trauma to the face, respiratory tract infections, allergies such as hay fever, immune system cells or cystic fibrosis.
It is important to find out the cause of chronic sinusitis as then specific treatment can be started. Treatment varies from saline and steroid nasal sprays to decongestants and antibiotics. Some resistant cases may need surgery. As for now, inhale plenty of steam.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
OK, I have used a "Neti Pot" u can get this at Walmart, it is cheap and it works, after you use it....mannnn. It feels so much better. They have saline packs that go in them too. This helps heal those tissues that are inflammed. Good luck!
