Multiple small red painful itchy lesions on the body may be due to allergic reaction
or bug bites or a generalised viral infection. Parasitic infestation like scabies
is also likely.
A direct examination of the lesions is necessary to make a proper diagnosis. You can consult your dermatologist
for the specific treatment.
I hope this information has been both informative and helpful for you.
