AngeliaNR, I've struggled with sinus infections for 30 yrs. One time it got so bad, I couldn't even drive. After DH took me to the doctor, DH had to tell me what I was suppose to do. I've also heard of the infection going into the brain. So, don't dismiss this, get to the doctor.
Now, when I get a sinus headache, I take decongestant and saline nasal spray. Finally found something that works for me to avoid the infections.
