I started taking steam since last week. Everything was fine with my breathing then. I was taking steam just as prevention. I was taking salt and turmeric steam by boiling the water in a pot and directly breathing in the steam from boiling water over the gas, but from a safe distance. But I am feeling a nose blockage for last two days. And today I noticed inside my left nostril the red part looks bit swollen which might be causing the blockage. Can overheated steam cause such problems? Any suggestions to alleviate it ?
