A little over a week ago, my boyfriend woke up with a cluster of small red itchy bumps
(4 or 5) on his arms
. At first, we believed them to be insect bites. In a day or two, they seemed to get better, but then more would appear (on his arms, an upper part of his chest which touches his underarm, etc... ). He thinks they spread when he scratches them, because his newest ones seemed to have worsened, as they have become redder and more blotchy.
