I'm not sure why you posted this on the hep C forum but I agree with the above. Go to your doctor or the ER and find out what's going on.
I agree with pooh. You need to go to the emergency room. There is no way we can tell you what caused your symptoms.
There is no way to know what caused the symptoms and what is causing the headache with out an exam. If it was me, I would go to the emergency room now and get an evaluation. Your symptoms could be caused by many medical problems, and some of them could be very serious.
