Yes and no. These conditions tend to be "self-limiting". I would not take anhything to reduce the temperature, but drink plenty of electrolytes, take a vitamin C and D3 supplment, plus zinc and magnesium, drink some carrot juide and get some bedrest. If you develop yellow sputem, develop difficulty breathing, or if the symptoms don't go away after four days, see a physician.
I would say yes...At the least, this is a simple virus working it's way through or strep throat...At worst, it could be viral meningitis..
