It appears to be tiny blisters on bottom of feet! Remind me of a blood blister under the skinDo not hurt sometimes itch. If I mess with them , they hurt and itch like crazy clear liquid if opened and hurts like heck..After a while they dry up scale off and a new batch reappear somewhere else on my sole of my foot. Do not cause discomfort or pain but sure are annoying . And now are starting to appear on both feet.........I think it s been going on for about a year or so one one foot . In the last month or so I noticed it on the other foot.
