Dear R_ddop, If you have any doubts for your own situation then just check with the doctor that knows your situation best... But in general, for most of us, yoga is a superb way to maintain health and well-being! The gentle stretching helps get the energy flowing for natural healing...here is my own story:
Around thirty years ago now, when I was age forty, my shoulder got terribly painful. And when the pain finally went away, the shoulder was frozen...I could not lift my arm above shoulder level. VERY inconvenient for things like washing your hair and getting dishes out of the cupboard.
The shoulder stayed that way for a year, and then I took six yoga lessons, one a week. By the end of the series of six, my shoulder had started to loosen up and for all the thirty years ever since then I have had full use of that arm! Apparently just got the vital force moving and carried off that arthritis or whatever was causing my problem.
So ever since then I try to do about five minutes yoga stretches every morning...plus it feels good...
Yoga is good for most people. It's stretching the muscles and making you stronger. When I do it, I think of it as relaxed exercise; unlike cardio which is 'high intensity'. And afterwords you'll feel really calm and nice. If you're considering yoga, go for the beginner levels first where the positions aren't as difficult. Hope this helped!
