Hello, im getting a little concerned with some bug bites that i got quite a while ago on my arms. Like 2 to 3 weeks ago i got bit five times in the same general area on my arm by mosquito bites, two of the bites have healed fully, but the other three flattened and then turned into little bumps that got itchier then when i first go the bites some scabs had formed in what im suggesting was the site of the initial bite, but now theyre little red lumps with a kind of deep whole in the center, they still itch from time to time and i don't know what to do
