Fluid Discharge From The Scalp After Itching. Need Cure

i have sensitive skin problem. especially on my scalp . it was all started when I scratched too much on my scalp and the next day it getting worst and worst. then after 3 days, liquid start coming out from my scalp every time i lay down or sleep. so the next day, i decided to wrap my head with towel and then sleep, even though my scalp is still sore i just keep sleeping then the next day, the liquid that came out from my scalp frozen and leave some liquid stain on my towel.. so i leave my towel on the chair and after 7 hours, there are so many ants grouping in the towel, as if the liquid is actually sweet :( maybe at night the ants bite my scalp after all this time? And its been a week now.
