I had a cold around 3 months back post which my nasal passage started getting blocked while sleeping - I faced difficulty in breathing. Also observed blood while blowing my nose. I have seen two ent specialists since then - the medication prescribed by the first one helped for some time but then this started happening again. The second doctor asked to get an X-ray, results were fine. Then he did endoscopy and said some outer lining is swollen. Then he prescribed 2-3 more tests and also said I will need to get surgery because this might be a case of deviated septum. I did not go back after that. The problem has worsened now and I'm having a lot of difficulty breathing. Do I really need to get a surgery done for this or medicines would work? Looking for a reliable doctor.
