Friend's son, age 4, has odd bump on foot...need assistance...?

I'm having trouble locating information about skin bumps that resemble a coin under the skin. Seriously, it's round and flat, but a bump, like a dime is under the skin. He's been itching it, and it seems painful. He had a fever last night of 100.7F, and has been extra emotional. The skin tone around the actual bump is flesh tone, but the bump itself is red/pink. And then the part protruding up from the flesh-tone skin is whiter than normal (this is 3 dimensional, like a cylinder, with the sides being whiter). There are actually 2 of these bumps making this configuration look like the figure 8. I'm running google searches...need help finding info. Suggestions? Would you take him to the doc??

Ringworm is flat,not a bump.It could be a spider bite or something.Definitely take him to a doctor,especially since he's had a fever!

Ring Worm!!!!!!!!!!!!!! He has obviously had it for a while!
Reply:I would take him to the doctor or the er. It sounds like it might be a bite of some kind since its on his foot. And by running fever it could have been poisonous, whatever it was, so I would get him to a doctor as soon as possible.
Reply:He has ringworm.He needs to be treated A.S.A.P. before it spreads.If it gets on his scalp then he will lose the hair where the ring worm is.The low grade fever had nothing to do with the ringworm on his foot.Go to the link below to look at the pictures of ringworm and see if they look like what he has.
