My tooth was extracted. The Xray showed my sinus were infected. 2 days later my face swelled up so I was given antibios. Now my face is swelling again?

See your dentist. Tooth extraction is a surgical procedure and is not completely risk-free. Pain, swelling and infection following surgery is usually at its worst 24 – 48 hours after surgery. After that it should subside more and more every day and after 7 days stop. Your symptoms could be a serous problem. See your dentist or an oral surgeon for post-op appointment and treatment.
