About a week or so ago, my legs started to get really itchy, mostly at night and early morning. A few days ago I noticed some small bumps
behind my knee, and they were very itchy
. A day or so later, those were mostly gone, but others had emerged on the back of my legs, some in small groups. They can get very itchy, but they are small and are not red at all (unless I start scratching of course.
