Can too much capsaicin actually hurt you?

I mean, obviously it hurts like a bitch.  But is the pain you're feeling directly related to any actual damage, perhaps at a much higher level of concentration of the chemical?

Edit: Just to clarify.  I'm wondering specifically if the feeling of pain and burning is because you are actually being hurt in some way.  It is absolutely fascinating to hear all these stories, though.  Godspeed, super-hot pepper eaters.  I could never be so brave.

Well, it's go an LD50 of 47.2 mg/kg, and if ingested it large quantities can cause abdominal pain and vomiting. Because its action upon neurones simulates a response to burning, the tissue at contact often becomes inflamed which can cause permanent damage, just like any inflammatory.

Dietary consumption is usually fine unless it's taken to extremes.
