Hello,
I have a history of OCD, and I have lately developed an intense fear of contracting something (like diseases
or colds). Recently my scalp has been quite itchy, and the back of my neck and ears are red, but I have no flaky dandruff. My father believes that it is an allergic reaction to something that I ate, but I eat the exact same thing every day, so I have ruled that out...
I have jumped to the conclusion that I have lice.
