My son is one years old. About two weeks ago he had done something to his thumb to were he developed a scab. It's right above his nail, now he has all of these little blisters going up his thumb all the way up to his knuckle, what is this?:confused:

Does it look infected?

Hi
I'll be fascinated with any answers you may get to this... my son has a scab on his knee from a fall that is taking its time healing... and now it's got these large blisters around it. I've googled it - but your ? Is the only thing that came up that was similar. Hope someone out there can explain what's going on... or it's another trip to the dr's :(

By the way it's not infected - just healing very slowly.
