I have sores all over my mouth that are big and keep getting worse. I have strep throat while this is going on. And idea what it might be? Also I have these bumps between my fingers.
Could be hand/foot/mouth virus (coxsackie a19) a common viral infection in the summer that usually affects younger people.
Can last up to 14 days, with blisters in throat, mouth, gums, hands and feet.
