Right now, I have evenly spaced red bumps
all over my body which first started from a itchy shin to red bumps
all over! I have searched up some reasons: scabies, chicken pox, hives, or bed bugs. Any of these are possible because they all have red dots. Try and check to see where your son's dots are, for example, underarms. If the red dots clumped together more in the more "sweating" areas, then it most likely is scabies (also, there would be blister-like apperances).
