What are these bumps on my fingers?

They are only on my middle fingers. Symptoms - tiny pinhead sized bumps that itch like crazy, off and on. When poped or broken a clear fluid will leak out for several minutes, they remain an open sore for several hours and then scab over. They appear along the sides of my fingers, and on top of my fingers. As they heal my skin becomes scaly and there is a white patch of dead skin.
