I would like to understand what is happening here. Dear Jay, thank you for your question. I don't have an answer for your question, because I can't understand how your wife can exercise so much on a treadmill without problems, yet can't sit up or stand still for more than 30 minutes. I have not heard of such symptoms before, so I can't suggest what the problem may be without talking to or examining your wife. I hope you find this information useful.
