For the past 4 years or so, every time summer arrives, I get these medium sized red bumps that pop up at random on my body. They are mainly around the ankle and foot area, but they also appears on my arms and last night, 3 of them popped up on the back of my scalp . They were itching so bad that they woke me up. The only thing that relieves the itch are anti itch cremes and hot water. They normally last for about 3 to 4 days before they go away and when they do go away, they leave a dark spot in their place and that too eventually goes away. I cant ever get to a dermatologist in time because by the time I get there, the bumps are gone. I now have an appointment set for October 12th but by the time I get there, they will more than likely be gone. What could these bumps possibly be?
