I have had normal cold and runny nose for sometime. My right nostril is usually hard and seems to have more mass than the left nostril. Suddenly mucus started developing in the my right nostril and it hardened and solidified and I started picking it. I kept on picking it and it was bloody and it solidified everyday and I kept on picking it. Sometimes the mucus was hard, sometimes tissue like sometimes soft, and everytime I used to do I sneezed our watery mucus like substance. All this while my left nostril is healthy and normal without obstruction and can be touched and bent. But my night nostril is now swollen, sore, and my nose looks a bit crooked because of this swelling. Please help me, what are steps of cure/prevention and medicines which I should be following for recovery?
