4 wisdom teeth out on friday. swelling worse than ever. back on blood thinner. sinus pressure horrid. what can i do for sinuses & to decrease swelling?

Pressure: First, i would see your ENT or pcp to make sure the swelling/pain in the sinuses is not a complication from your procedure. Especially since you are on a blood thinner. Use ice for now- no nsaids, asa, intra nasal sprays or oral decongestants.

Call Surgeon: Call your oral surgeon now. He/she has your medical and dental histories and is best positioned to help you through this.
