Background: What is Papalomoya?
Papalomoya is the common name in Costa Rica, Nicaragua, and other parts of Central and South America for cutaneous leishmaniasis, caused by Leishmania parasites transmitted by sandfly bites. It creates slow-healing skin ulcers, often on exposed areas, that can last months to years, cause scarring, and sometimes involve nerve pain.
Standard treatments are antiparasitic drugs such as antimonials, miltefosine or amphotericin B. They can be painful, expensive, hard to get, and carry serious side effects. In Amazonian traditions, tobacco has long been used on wounds, infections and parasites.

My Experience: How It Began
In early 2023, the pain felt like a deep bruise or blow to the shin, with no visible injury. I also had radiating pain from my heel through my buttocks, likely sciatic nerve involvement, which I first blamed on standing work. Over four months, a small sore emerged from under the skin, grew larger, and became intensely painful.
I saw a skilled dermatologist in San José, Costa Rica, who initially treated me for vasculitis. At my follow-up a month later, a second lesion appeared, raising fears it was spreading. She then suspected leishmaniasis. Hospital PCR tests on the dry wounds came back negative twice. Sampling issues with dry lesions are common. Despite this, the symptoms matched leishmaniasis perfectly from my research. In June I tried ivermectin, with no change.

The Tobacco Treatment
By September 2023, eight months in, the pain was excruciating: no pressure on my heel, couldn’t sit comfortably, and nerve pain from heel to buttocks made sleep impossible. The dermatologist mentioned government-hospital injections directly into the wounds, twice weekly for a month. Horrific and unavailable privately. I refused.
