I get that all the time, it's like scab tissue from your sinuses from using too much. After about 30 days off, it pretty much heals up. If you use for like a couple weeks straight, your membranes get so ulcerated that you can't hardly get a buzz anymore. Try not to blow your nose real hard to dislodge them, cause it'll hurt like hell. Occasionally I'll have one fall down in my throat, talk about gagging!
