hello, I have been getting large amounts of small to medium sized acne looking bumps all over my scalp. I remember working out in the sun for 10 hours and getting a really nasty sunburn, about two days later, I got these oozing blisters on my scalp that would literally ooze out forever. Once that healed up, I started getting small red bumps on my scalp that were really itchy and get itchier everyday, what can it be and how can I get rid of it...???
