Had impacted wisdom tooth@cyst (upper) 5dys ago gen anesthetic spitin blood think it comin from nostril blowin nose showin blood to can u advice please x?

Sinus perforation : Apparently while removing the cyst abd the impacted molar the sinus got perforated . That is why you see blood when blowing your nose . Did you check with oral surgeon who had performed the surgery on you for follow up . Please do and he will explain it to you and direct you on how to deal with it .This situation is not uncommon and it happens many times

Contact your surgeon: This is likely normal postoperative bleeding, but you should contact your oral surgeon so he can take a look at you to be sure.

Sinus communication: Hopefully and oral surgeon performed the procedure and will see you for follow-up. Sounds like you may have had a maxillary sinus perforation/communication. You should be on antibiotics, i.e. Ceftin, (cefuroxime) a decongestant, i.e. Clariten-d, and avoid blowing your nose, spitting, or drinking through straw for the next 21 days. These usually heal uneventfully, but sometimes require surgery for closure.
