Throat. About 10 years ago I had sinus surgery to correct a deviated septum. I also wear a CPAP machine nightly I have triedthe Saline solution, I have tried generation one and two allergy medications, I took allergy shots for 12 years which did help for a period of time. I have tried taking Mucinex that has acetaminophen, a decongestant ( phenylphline, and gualfinesen. I take one to two a day but not every day. I have been told that if you take it too often it can have a rebound effect. I need to know what would help to do away with this sinus pressure that makes me Spacey and almost Dizzy at times and keeps me from being clear and alert on my job. I’m a senior adult but I still work part time and I would like to feel good.
