Yes, I have sinusitis and my nose is always blocked. In severe cases, I always have a headache, and I can feel the pain from my nostrils and sinuses to my head. I drank a lot of grapefruit enzyme last winter and my nose was no longer blocked and my head ached no more. But my nose kept running clear. It is estimated that grapefruit enzyme is responsible for the coolness. In the summer, I finished drinking grapefruit enzyme. Less than two months later, my nose started to become blocked again and I also had headaches. So I made another big bottle of grapefruit enzyme, but what should I do now? I can't do anything because I have a headache, and I can't sleep well at night because my nose is blocked. Two days ago, I suddenly remembered that enzymes can sterilize and reduce inflammation, so I dipped a cotton swab in the original solution of environmentally friendly enzymes, inserted it into the nostril to the sinus area, two or three times a day, and let the cotton swab stay in the nostril for about ten minutes each time. I worked on my nose for two days. Not very clogged, especially when sleeping at night. The nose is not blocked, and the headache naturally disappears.
