For 2 years i have difficulty breathing. i have shortness of breath & can't breath through my nose unless im sleeping. have to bend over & breath deep.

Sob: Your shortnessof breath may be due to a nasal polyp or deviated septum. Consult an entspecialist for evaluation anf d treatment.

Need ENT/ allergy: And pulmonary consults. If everything has been tested and has come back normal but i would recommend that you get a referral to a tertiary care university center for a more high-level evaluation. I can't tell if your ocd perhaps even plays a role in this. You should have your psychiatrist on board with these consultations. Hopefully with everyone putting their minds together they will be able to come up with a solution to your problem. Best wishes.
