I'm sorry you are feeling so badly. I used to have very similar symptoms from September to mid-winter, from March 'til July. Then I got allergy testing, started on allergy shots, and then moved on to allergy drops. It takes a few months for allergy shots to really kick in, but if you continue with them faithfully, plus take your annual flue shots, "cold/flue" symptoms can become a thing of the past. What was once a demon illness that plagued me most of the year around is now . . .gone [knock wood, of course]. It's allergy season. Allergies produce histamine, which cause all the cold symptoms, like congestion, drippy nose and sore throat. This, in turn, becomes infected sinuses, bronchitis, pneumonia, and what have you. It really could be that simple. And in this manner, you can, in future, avoid all the courses of antibiotics needed to settle down these respiratory infections, antiobiotics which kill off healthy, as well as unhealthy bacteria, leaving the individual with compromised immunity. Typically, a good brand of Acidophilis [good brands tending to require refrigeration], also found in those plain brands of yogart which so state on the container, will tend to restore a favorable balance of healthy bacteria in the digestive system. Allergy testing is very easy these days. You can literally lie there and go to sleep during the procedure. Once you have the results, serum is made up especially for you, and you can either inject it or put the drops under your tongue. Drops are more convenient. Best of Health Restored to You ~ billieJ
