I have bumps that are extremely itchy on the back of my ankles, on both knees, my elbows, and thighs. I notice when I am stressed they flare up in the same spots each time and when they deflate they leave marks and they pop back up in the same exact spots every time . My dermatologist says it is eczema. They gave me a steroid cream but it does nothing. Not sure what I am dealing with any suggestions? Again they are bumps not blisters, they are individual bumps , not clusters of bumps. They go up and then they go down. Thanks
