I have a infection in my wisdom tooth thats spreading to my palate what can i do?

You need to see a dentist ASAP for a proper diagnosis and antibiotics. Once the infection is controlled the tooth needs to be extracted. Failure to treat can allow the infection to spread into your sinuses, and in extremely rare circumstances travel to your brain.

You can't treat an infection with a computer click. Please immediately see your Dentist or a specialist Oral Surgeon for care, probably antibiotics to control the spread off the infection, and then extraction.
