You are right on track. Be sure to "warm up" a bit with a lower pressure and then go to what you're comfortable with.

Thanks! I do find that "warm up" advice especially helpful. I've been doing 15 minute sessions, moving the cups around a bit from session to session. After 5 minutes I find myself wanting to pump a little further, but wasn't willing to go there, at least until the contusions healed (using Arnica gel for that, works wonders).

The bruising is almost gone now, so it seems I can do that 5-minute warm-up thing, then keep increasing vacuum through the rest of the session as I feel "ready" for it without getting to the blushing/tingling state.

Is that right? And 15 minutes is what Kangzhua instructions recommend. Is that correct? Or could I go longer with good effects?
