During the recovery at home, what can I expect?
Be prepared to go home and finish your recovery there. Patients often experience drowsiness and minor after-effects following ambulatory anesthesia, including muscle aches, a sore throat and occasional dizziness or headaches. Nausea may also be present, but vomiting is less common. These side effects usually decline rapidly in the hours following surgery, but it may take several days before they are gone completely. The majority of patients do not feel up to their typical activities the next day, usually due to general tiredness or surgical discomfort. Plan to take it easy for a few days until you feel back to normal. Know that a period of recovery at home is common and to be expected.
