Unknown skin irritation

Yesterday morning I woke up and my palm was itchy. I scratched and once it stopped itching i saw it was a very small bump with a clear liquid inside. So I popped it, and as soon as I did that my other palm began to itch and three of the exact same bumps appeared. So I washed my hands really well and put some neosporin on my bumps. I was fine all day, then later that evening the top of my wrist itched like crazy and about ten of the little bumps with a clear liquid appeared. My legs itched not long after but nothing happened, then my foot itched and one popped up there. So I am confused as to why nothing happened to my legs when they itched. I took a bath to see if that would help the itching and it did and I put neosporin on all my little bumps and they seemed to be going away, but then my palm began itching again today and the bumps reappeared. I do not know what its from or what I should do to get rid of it. If someone could please help I would appreciate.
