For Three Years I Have Experienced A Strong Sensation Of

For three years I have experienced a strong sensation of itching along raised mounds of skin, if I pick these mounds (the itching often compels me to do so) the itching stops, days later flesh around the site becomes inflamed and itches, if I pick these sites, a great deal of dead flesh around a hair follicle comes out as a single piece of translucent, white, moist dead (not scabbed) flesh. This will stop the itching, for a few days, then the flesh around this site will inflame and itch, and a new ring of dead flesh will be pulled out. This appears to have all began after I entered a rental to clean it out, and hundreds of baby fleas, literal hundreds, swarmed me and bit me for half hour or so until I could buy poison and douse myself in it. I have no clue what this is.
