My first CH experience was 1983 when I was in 10th grade (age 15). I was diagnosed by a friend of mine that was a MD/Ph.D when I was 25. Symptoms were periods lasting 4-6 weeks with 2-4 attacks per day, repeating every 10-14 months. For first 10 years I self treated with ice (applied to head/eye) and chewing 2 Tylenol Sinus for immediate effect. This continued until 1999 when I read some scientific articles about the effect of intranasal capsacin and applied ground red pepper all over the inside of my nose. This aborted the attack immediately (~20 minutes instead of usual 2-4 hours), and with repeated treatment for all attacks over next 7 days it shortened the usual 4-6 week season to just about 2 weeks. I treated with capsacin on the next attack about a year later, and again it shortened the season to just about 2 weeks. Then I was in remission for about 3 years, then after self-administered capsacin in remission for 5 years after that. It's been 4 years since the last attack. If it returns I'll treat with intranasal capsacin again.
