My son has bumps on tougne,gums,inner lips, cheeks, arms,hands,legs,feet. He won't swallow his own spit and it seems like he's getting worse. The dr said he might have some kind of hand,arm, and foot disease or measles. but she won't run test or give him meds. what should i do and what do you think it is?
