If you have had your tonsils removed, that may promote the movement of infection into the chest more easily. I've seen this happen with my Mom and my Husband, both of whom have had their tonsils removed. My Brother and I still have our tonsils, and colds/flu tend to stay out of our chest or to not be quite as severe for us.
Also, antibiotics do NOT treat viral or fungal infections (although viral or fungal infections can sometimes enable secondary bacterial infections to take place), and in some cases may make the infection worse (because the antibiotics will kill off good bacteria in the gastrointestinal tract, which can then lead to fungal infections in the gastrointestinal tract or elsewhere in the body, and can also make a person more susceptible to other kinds of infections). It might be good to look into nutritional and alternative methods of treating your infections if the antibiotics are not helping. Naturopathic physicians may be of benefit, especially for viral & fungal infections that are not responding to treatment with regular MD-prescribed medications.
Good luck,
