He has been seen by four different doctor's about this and no one knows what is going on. The bumps
will begin as a small to large red bump
, much like
a mosquito bite
, but within 24 hours they will have a blister on top. The bumps will usually last about 5 days and then start to go away. Once they go away, some will leave scars on him as a small round bump. He has had them on his arms, feet, legs, stomach, back, etc.
