Yes there us a way to make them heal faster and it's one of the best things to come on the market in the past 7 years. They are sold in almost every pharmacy and grocery chain, Bandaid Blister bandages are brilliant! They are expensive but you will only need one or two at the most. They come in different sizes so be sure to get the size that will fit the wound. Apply carefully, read the directions, don't put anything greasy on your skin like neosporin, you don't need it. The bandage seals and almost becomes a second skin. The speed of healing is almost miraculous. You blister will be gone within a couple of days. Best of all the pain will be relieved immediately.
The blister will heal depending on how bad it is, although it might take about two to four weeks to heal. You can get rid of the blisters fast, by rubbing methylated spirits on them. This will disinfect them, though it is extremely painful on open blisters. Visit http://walking.about.com/cs/blisterschafing/ht/htblisterfix.htm for more details.
