I am having some group blisters in my hand in a line form and one or two in centre of chest below neck. This starts by some irritation in hand and when i rub it blister forms. This usually comes while i travel in bike for more than 60km in mng and eve.(total - 120km). but the blisters subside and the clear fluid is absorbed by the body itself within 2 to 3 days. Does pemphigus goes away within 2 days?. I hope this may be due to insect bite. But what are the symptoms of pemphigus. No pain or itch in the area of blister.
