Suggest Treatment For Itchy Bumps In My Feet

I have these small, itchy bumps on the bottoms of my feet. I pop them and a clear liquid comes out. I had athletes foot and used a spray to get rid of it. All the symptoms went away, but the bumps stayed. What do I do? I'm 25, 5'6" and 150 lbs. I have a good, healthy medical history.
