i have an itchy patch on my scalp, the area starts at about 1/2 inch but expands to 1.5" diameter after few days, it swells and gets tender and looks like a bunch/clusters of white puss balls overgrowing each other. after I scratch them it turns scabby but after a day puss balls form under and around the scab and this tender area gets bigger and bigger to 1.5" in diameter. this goes on for a week or 2, it eventually goes away. but then comes back in few months.this is the 3rd time its reocurred this year. I thought it was a spider bite, but after it came back in the exact same spot for the 3rd time, I realized its something else..Can anyone help? I dont have a deramtologist and really cannot afford professional help/doctor right now.
