Hi GomezNC, I hear you, that happened to me a lot. I had an infection for ten years. I used to get so sick all the time too from colds and virus, and used to get sinus infections constantly.
Since being on antibiotics and thyroid meds plus adrenal support for about 10 months I am finally doing better. My doctor tested my immunoglobulins and they were good. Finally!
A product that is extremely helpful to me whenever I am exposed to someone else's germs is esberitox. It boosts the immune system and I keep it in my purse. If someone even sneezes near me I pop a few of those and it has helped so much. Many of my friends are singers (me too) and we use them if we have to sing and feel a little cold coming on. It kicks the cold right out of us if we catch it in time. If you have a full blown cold it doesn't work.
I hope your immune system is strong soon. Do all you can to build up your body by putting good things in. I stay away from alcohol, sugar and caffeine and that helps a lot. Better days ahead for all of us!
