Weird tingly itchy rash type thing on the palm of my hand..?

I have tiny tiny bumps on my right hand, there's nothing on my left. the colours weird to, like when you press your skin hard and it turns white, but it's tiny pin prick size dots all over the edges of my plans and my fingers, and my pinky finger has a couple reeeeeeeaalllyy small blisters my palm is very itchy and is tingly to like when I scratch it or make a fist or put any kind of pressure on it.. its happened before, and I thought I figured it out I thought it was a cedar allergie but I got rid of the cedar more than 6 months ago and I'm still getting it so now I'm lost cause in the past few days I've handled nothing new that i could be allergic to. aloe Vera gel and cold water seems to help for a bit does anyone have any ideas what it could be?????
