Don't really want to go to the doctor...?

OK...here is the deal....Thursday I woke up with a sore throat. Didn't think much of it b/c here in NE Oklahoma we have had ALOT of rain and still getting some, so I thought it was just my allergys. Then later that afternoon my whole body started aching and head starting hurting. Took some alka-seltzer for flu symptoms and all was good for awhile. Went to bed last night. Woke up this morning with sore throat got up and got around then started feeling like crap again! Took same meds. All day today I have felt weak and dizzy plus the sore throat and not to mention TIRED!!! Any Ideas???
