I answered on your other post. I sincerely think this is more of the anxiety and OCD symptoms you have experienced the last few months hon. Please talk to your ob/gyn. I'm beginning to worry about your baby once being born as your anxiety is so high. Sinus infections are secondary typically to a cold and a cold is a virus. When my family gets sick, it is not unusual for multiple people to get sick. And it IS that time of year.
Hello~I hope everyone is feeling better by now. Quite possibly it could be due to allergies, do you have a fireplace? Many people are allergic to the wood that they burn. It could also just be due to the season, winter seems to be the time when many get colds, flu and other miserable issues.
