Severe sunburn strange symptoms, see a doctor?

I got a sunburn a few days ago, it seemed pretty bad to my friends and family but I don't feel any burning pain, have any blisters, and although there is redness by now it is almost completely gone(it's been three days). However, a day after the sunburn I began to experience flu like symptoms, it started with chills, nausea, high fever. During the second day(yesterday) the fever went down a little in the morning and increased again in the afternoon. I've been taking aspirins. My nausea has improved, and I've been able to eat again. Now I have a runny nose and a sore throat, but still feel little pain.

I've had a friend feel my forehead for me to see if I was burning up, but she said it felt like only a degree or two above normal body temperature.

I'm not sure what to do. I'm probably going to see a doctor today anyway, but I don't know if I'm overreacting. Could it just have been an unlucky flu that happened at the same time of the sunburn(or even a day later?), and should I just take acetaminophen for it?

I've been drinking water to the point where I'm peeing almost clear. Taking aspirin seems to lower my fever and relieve the little pain I feel, but I can't keep taking aspirin forever. Help me out!
