Finger bumps
9 Answers
When it's exremely hot, red bumps of different sizes (ranging from pinhead size to larger) appear on the first joint of my fingers, and spread. These last almost a month and go away on their own. They're itchy, but not painful. Is this caused by heat or is it something more serious?

I have cold urticaria, which produces the same symptoms (itchy hives & tiny bumps on my hands and arms) after exposure to cold, particularly moist cold. But there's all different types of urticaria, including heat and solar urticaria.
