I Think I May Have A Sinus Infection. I Have

I Think I may have a sinus infection. I have penicillin vk 500 MG from having my wisdom teeth out a few months back. Is this something that I can take that will help? My face is swollen. My tonsils are swollen and my upper teeth and hurting. I need relief and don't know what to do. I am flying out of town tomorrow and don't have time to go to the doctor. Any advice would be appreciated greatly.

Thanks
