I get transparent bubbles on feet. they don't pain. what is the problem with me.?

Mmp: Matrix metalloproteinases are enzymes that destroy skin it is expressed in people with lymphedema, diabetics, on meds like coumadin, (warfarin) steroids etc. To control them use orally vitamin k2 (subtype of vit k) and zinc, selenium. Locally you want to protect the skin with wrapping them with calamine soaked gauze (unna boot strips) and webril with tubular stretch bandage so skin does not peel off.
