my 5year old son got itching on his legs continuously, and rash-like spots or welts are appearing on them. what should I do?

A. Apply calamine lotion this will be helpful you can also use EVION vitamin E cream or Atogla all these options are very good I think this is just some kind of rash that’s spreading also check with your doctor because you need to have a better understanding of the reason behind the problem also Dr will give you better advice on the same
