I have these big itchy bumps on my skin it started on the back of my arm right above my elbow and at first i thought it might be a mosquito bite but then i woke up the next morning and i had another on the opposite side of my arm and then within the hour i had another below that one. The next day i had one on my leg the one on my leg is pretty large and they re all kind of hard. There s nothing coming out of them but they itch a lot
