Take invisible suffering seriously so you can have your invisible suffering taken seriously when you have it!!

The world's most painful condition demands urgent action. Help us accelerate access to effective treatments for cluster headaches.

**About cluster headache**

Cluster headache ("suicide headache") is often considered the most painful medical condition. Patients [rate it](https://doi.org/10.1111/head.14021) as significantly more painful than childbirth, kidney stones, gunshot wounds, and bone fractures. Standard painkillers don't help.

Even in wealthy nations with advanced healthcare, **hundreds of thousands** still experience torture-like suffering every year. About 50% of all patients have contemplated suicide. At the same time, global funding for cluster headache is virtually nonexistent. **This crisis cannot go on any longer.**

**Psychedelics save lives**

Psychedelics like psilocybin, LSD, and DMT have shown promise in treating cluster headache pain, in some cases with 70–80% of surveyed users reporting significant relief. Some patients even achieve complete remission.

Often, low, sub-hallucinogenic doses are more than enough to prevent clusters or stop attacks acutely. Patients could self-medicate safely and with minimal side effects.

However, only a tiny minority of patients have access to these life-saving treatments. Given the severity of the pain, the situation is analogous to refusing anesthesia to patients during surgery. **This is absolutely unacceptable.**

We need your help to accelerate access to effective treatments.
