I have the same blisters and I pop them when they get big. I only get them on my right foot in the arch area. I have only found one thing that works. I wash my foot with apple cider vinegar. Only once a day right before I go to bed. It smells kinda strange but it's the only thing I've found that works when I stopped using it the blisters come back. It's the strangest thing I've ever heard of but what the hell it does the trick. Try it for a week or two you'll be happy you did.
I too have these blisters. They always come in clusters of 3 and don't get very big. I pop them and a few days later the skin around them dries and can be peeled off. They are usually located on the inside of my left foot in the arch right where the skin changes from side of foot, thinner skin to bottom of foot, thicker skin. I didn't start getting them till I was about 26 or 27 years old. I am now 41 and get these little rascals 2-3 times a year. I was wondering if anybody else ever took Accutane. I can see it being a fungus like athletes foot but I just wonder if there could be something else beside a type of athletes foot.
Most likely caused by Candida overgrowth, which also can cause abdominal pain. Candida lives on sugar. It's interesting to learn about if you have the time.
I found two things I think might help. The name / names of the problem. Pompholyx Eczema and Dyshidrotic Eczema. They both look just like what I have. I didn't study long enough to figure out just what the differences were. But a Googled, "Dyshidrotic Cure" and came up with a bunch of great info from people who have had it and cured it. I think knowing what it is is half the battle. So very thankful for the internet!

I feel your pain! I am just now getting desperate enough to research what's causing this. I am still researching but I know that most likely I'm going to have to do a major diet change. I really think everyones problems are stemming from unhealthy malfunctioning bodies. The only real cure is to get healthier and help your body heal. I'm specifically looking into gut healing and liver. I hope you get relief fast! Your must be worse than mine. I'm so sorry!
