I asked this question before, but the post got spirited away with a vague "I'll have one of our experts answer this via PM". And since attempts to follow up and get that answer have failed, I thought I'd re-ask.
When I use HOT-ROX, I get a runny nose. Starts after about half an hour and lasts for maybe 2-3 hours. After that, it goes away. Has anyone else experienced this? And does anyone have ideas as to why this happens?
