My sons symtoms started with a bad headache followed by the chills, fever of 103 over the weekend, spitting up mucus,fatigue,difficulty swallowing and all this has taken it's course. Now white pus patches on the right gland has appeared and now no fever. He's doing the warm water with salt to gargle, plenty of liguids and is able to tolerate solids some. He's been seen by the doctor with similar symtoms and has taken over the counter Mucinex and no actual signs of strep. Please advise. Thank you.
