When will this subside?

It's been 5 days after my impacted tooth extraction but my right cheek is still swelling like crap. I don't know if the headache I'm feeling is related to this but it goes away few minutes after I've noticed it. It still on the treatment my doctor told me.
*Saline gargle after eating
*Antibiotics 500mg 3x a day every 8hours
*Cold compress for 10 minutes
*Avoid giving pressure
*Gentle brushing to avoid the wound


I follow each of these orders and I want to be better but I'm not feeling good at all. I sometimes tend to be a hypochondriac where I always think of the worst that's gonna happen to me if ever. Anyway, here's what I look like and I don't like it at all. ;(
