I have red bumps with black centers that have appeared and keep on appearing this evening. Upon further inspection...i see tiny tiny red itchy spots on top of my foot and around my ankles. Then i have slowly watched as larger pimple sized bumps with a black dot appear on my calves, then my thighs, very little on my hip area, and then the larger red hives like bumps have slowly kept on appearing on my back. they have raised, large blackhead like centers. I tried squeezing these one and only on one the center came out. I keep watching them appear. There were no blackheads where these bumps formed. I have some moles and freckles, and maybe some tiny tiny clogged pores here and there. But not this! The only itchiness is the spots on my ankles. Any ideas of what this may be?
