True healing requires recognition of these factors. I do most of my stretching and exercise in the pool. However even that has caused severe flare-ups of pain . It is important not to over stretch. To stretch intelligently requires attention to the body with accompanying awareness of breath.
Many people injure themselves by incorrect stretching.
It is a common problem. Stretching without attention to breath is not very intelligent. It is important to interview a yoga teacher or yoga therapist just as you would a new doctor or dentist. Make sure they are aware of your special problem or needs, that they are gentle and therapeutically oriented in their approach or training. Look for a professional credential and for instructors who are also nurses, doctors, physical therapists and other another health professional who also teaches yoga.
