I have had problems with sinus infection off and on for the past twenty years or so.
I had it pretty bad about a month ago and then it left and it is back again.
Woke up at three am this morning and the room was spinning.
now this is different then vertigo which I have had and have to say it is the worst thing a person can experience.
It is awful.
But sinus infection is bad enough.
Have medicine for it, over the counter stuff that I literally have to sign my life away to buy, (it contains whatever meth makers need for their drug)
but it helps fairly well.
