Cut them. ALLLL of my blisters i cut. Disinfect a knife or needle, poke into on an angle like this:
---------->/
^Knife /
Be sure to go slow and stop once you see fluid come out, i HAVE done this on blood blisters, too! Apply some disinfective, and let dry for about a week, in your case. Then, Cut off the rest by opening up the hole you already made and cutting on the edge of live, and dead (blistered) skin, and cut it all off. ONLY WHEN SKIN IS HARD, DRY, AND DEAD, otherwise it will hurt... ALOT! if its dead, you dont feel it. DO NOT PEEL, that can cause live skin to rip, and that hurts even more.
Im 100% not kidding, if done correctly, in about a month or two it will be gone, no scars!
