Yes, this is snuff-related.
I started experiencing extreme pain in my left leg, saw the toes of that foot intermittently turning purple, and felt my hands getting very cold. I went to a doctor, where I was diagnosed – after many tests – with Buerger’s disease (Thromboangiitis obliterans), “a recurring progressive inflammation and thrombosis (clotting) of small and medium arteries and veins of the hands and feet. It is strongly associated with use of tobacco products, primarily from smoking, but also from smokeless tobacco.”
That’s from Wikipedia: https://en.wikipedia.org/wiki/Thromboangiitis_obliterans
I’m not here to lecture, so I’m keeping this short. I’m one of you. I love exploring, buying, and taking snuff. I’ve been a member here for years, mostly lurking. Check my profile. I didn’t just sign up to scare you. Buerger’s disease only affects susceptible individuals. You may not be one of them. Then again, maybe you are.
What I am asking is that you read that Wikipedia article so that you know the symptoms, and, if you start to experience pain, numbness, color changes, or cold in your extremities, that you see a doctor immediately. I’m being told that this is an irreversible disease, but that cessation of my tobacco use is the only way to slow its progression. I’m giving up something I really enjoy, and hopefully I’ll get to keep my foot. Keep an eye out, fellow snuff-takers. Please.
Best of luck,
