I was not able to get a flu shot this year. I used to rarely get sick in the past few years (5 years or so). Anyhow, I keep getting a cold (runyn nose with greenish mucus, no fewer or aches) every two weeks. The first time in Oct, then in Nov I did not go to a doctor and just did home remedies. When I got sick again in Dec I went to the docs and got penicillin, 500g 3 times a day for 10 days. I completed the course. But here I am two weeks later and have a stuffed nose again. I'm planning to go to the doc again and have a appointment later in week, however was curious should I be looking for something beyond a cold. I also have allergies, but only in spring due to pollen, could these be allergies, or maybe allergies that end up giving me a nasal infection.
