Suggest Treatment For A Blister On Toe After Bruising

I have recently been to a podiatrist with a small break on the top of my foot just below my big to. I hyper extend the toe by stubbing it into oak dresser. It was wrapped for ten days. Day 8 the bottom of the big toe started to become sensitive by day 10 the pain was so bad I could hardly walk into Dr s office. The cut the bandage away to reveal several large blister. The docter tried to drain some of them with a needle. She felt it was an allergic reaction to the tape. But the rest of the skin on my foot was fine. I was told to use gauze and latex free tape. Soak twice a day in Epsom salt and us anti bacterial cream on the blisters. That worked for a few days but now I have a new huge blister on the top of my big toe. These blisters hurt! I don t know what to do because the break is not really healing, its still swells up and these blisters are adding to the pain. I m concerned about why I m developing these blisters. Help!
