When I scratch my foot, blister-like-bumps are filled w/ blood when popped, is their any remedies to stop/soothe it without going to a derm.?

Yes...but. While "blood blisters" are common from trauma, & generally do not need specific treatment other than time, the way the question is asked concerns me.If every time you scratch or have minor trauma to your foot you get blood-filled bumps, you should be seen. I would be worried about a bleeding disorder.General wound care:soap/water/air/aloe can all help injured skin heal.Slow healing think diabetes.
