Hi Terri,sounds like a good idea to improve cardio fitness but I don't think this will improve the lymph oedema in his neck. Mainly because jumping / bouncing won't move his neck muscles to the degree that is needed to shift fluid . However I will be interested to hear if this does improves Jeffs symptoms. Can't hurt.
Don't Jeffs docs have any suggestions to help? Kris still has lymphoedema in his neck but it is certainly improving. We were told it would take 9 to 12 months to subside..
