Hi Diana,
Welcome back. I guess you have to talk about this with your doctor. If you can't bounce, I would think it is only the case, as you recover. I would be suprized if you were banned from bouncing for life!
Maybe you could substitute walking in place, if bouncing is out for awhile. Walking has an association with qigong. It can warm you up, and it has a rythmn that can effect heart rate and breathing. You can walk in place faster to produce warmth, or slower , and also can slow down heart rate and breathing. You can also really relax while doing it.
Shawn,,, interesting what you say about the significance in bouncing, and how that may show up more. It is utilized in martial qigong too, both for health, and as a basic expression, of a type of power. I focused more on it yesterday, after I read your post, and did it a bit longer. It felt good, purposeful, and really generated some warmth. Another one of those qigong exercises, that probably looks a bit odd to the outsider! -gallen
