Here's an ointment I invented for my grandmother's arthritis, just be careful with it if you're sensitive to peppers or have sensitive skin.
1 c oil
3 Tbsp Cayenne pepper powder (about 4 dried peppers ground)
3 Tbsp fresh ground clove
Grind the Cayenne pepper and the cloves together, add to the oil in a stainless steel, glass, or other non-reactive pan (avoid aluminum and cast iron). Bring to a low simmer, the oil should just start bubbling. Turn off the heat, let sit for a few minutes, then turn the heat back on and bring it back up to a simmer. The heat used for this should be as low as possible, cause if you get this too hot you'll cook out the medicinal properties. Once your oil turns a nice red brown color, let it cool and apply it over the joints that have pain issues when you start hurting. You can store it in a reclaimed glass jar, just keep it in the dark when not in use. As with all things with capsaicin in them keep it away from your mucus membranes. I've not found washing the hands after the oil has soaked in to be detrimental to it's function. My grandmother is also constantly rubbing her face, forgetting she's just put this on her hands and only rarely has she had issues with it hurting her eyes or such.
I hope this can help you as much as it helps my grandmother.
