i get these blister like bumps. when i say blister, they feel like the pus of a blister, but the skin is raised. they itch, so that's what draws my attention to them. i get them on the tops and bottom of my feet, in my pelvic area, below my rib cage. sometimes thay appear in clusters on my back near my spine. they usually appear in the evening and are gone around 8-9 in the morning making it hard to go to a dr for treatment. at first i thought i was bitten by a spider, but now i know that's not it. i have not been able to link it to soaps or foods or an allergy type thing. i have had this going on for about 3-4 months off and on. i am a 41 year old female with no medical history. i have never had any health issues. i have only been hospitalized for the birth of my 4 children who were born all natural births with zero complications and range in age from 22 down to 15. any thougts or suggestions?
