There is a natural product I use that will knock a sinus infection out quickly and I’ve recommended it to people who say they keep going to the doctor for antibiotics and it always come back worse. Costs about $11 now and I get mine at health food stores. I hate taking antibiotics because they seem to weaken the immune system.
I went through the similar situation a week ago. I was sick and had a lot of cough. But I guess you should first try home remedies, steam, hot soups etc. It could be due to season changing.
