I woke up with a bump in the baggy area under my eye. It is red with little white pustule like dots (pinhead size) on it and there is swelling under my eye. It happens maybe once a year. The bump starts out dark purplish (like a bruise ) and then becomes red and inflammed. Could this be associated with stress or the fact that part of my thyroid has been removed? It presents very much like a spider bite but can t be, as it happens about once a year and goes away within a few days (the swelling lasts a bit longer). Any ideas?
