bubbles under skin on palms

Hi...

This may or may not have a connection to my larger symptoms but this is something I have experienced a handful of times over the past couple of years and I have an "outbreak" of this right now.

There are little bubbles filled with clear liquid just under the skin on the palms of my hand. They're very small and gathered together in clusters. They eventually reacht he surface, ooze out, and then form a scaly scab that eventually wears away. They have also been itching sporadically.

Does anyone have any idea of what this may be?
