From what you've described, it seems like a infection of the throat. It can be viral or bacterial infection. Spots that itch are called urticaria
and if itching is bad, it needs special medications (anti-allergy
) which will relieve itching. Since fever
has been persistent, I would advise to get him checked over again by doctor both because of persistent fever and urticaria.
I hope he is taking orally well, has good number of wet nappies a day and is not too irritable/clingy.
