My T has certainly pushed me rather firmly towards discomfort. I wouldn't say she's tried to keep me there, in discomfort, for longer than necessary. To work though it, it does need to be looked at and examined though, I've found.

That was my first interpretation of holding in discomfort, though I'm sure it could mean supportive holding as well. I think I would have read it as supportive holding if you'd said "hold you through the discomfort".
