My boyfriend just had a lipoma removed from the side of his forehead today. It has been about 6 hrs since the procedure and the doc told him he would have a splitting headache tonight. He tells me that it feels like somebody has ahold of his eyeball and either pulling it or pushing it. The lipoma was deep and the doc told him he could see his skull post removal. Also he had to cut a nerve that was supplying sensation to his forehead. What is causing this eye pain?
