What is this on my T's abdomen?

What's this orange mark on her abdomen? I'm a little worried about it as she isn't ready to molt yet. When i lightly brush her with a paint brush some brownish looking stuff comes off. Should i be concerned?

Looks like the beginning of a bald patch due to the T kicking hairs.

That does make sense. I just got done giving her a new clean enclosures. After that my face and neck started feeling really itchy. I guess i know why now.

The brownish looking stuff you brushed off would be urticating hairs.
