Hello sir, in the picture you Posted there appears to be ulcers on your cheek for which apply an ointment Tess/Dentogel 3-4 times a day till the ulcers heal. Since you have undergone extraction 2 days before you might feel some discomfort but if it persists for few more days I would advise you to visit your dentist and get it checked

Don’t worry the area is sore because of injections and the extraction procedure. It will heal within a few days. Have cool and soft diet for a few days
