Namaste, Kiran,
I have been on holiday - sorry for delayed reply. Others are more than welcome to give their opinions and help to create an interactive community of yoginis and yogis sharing their experiences.
In my experience, the rolling bridge pose as I learned it from Mukunda Stiles has been of tremendous help for me and my yoga students as a therapeutic treatment of back pain. I have found it to be helpful for pain relief throughout the spinal column when done slowly, progressively, and with attention to the physical response of the body. For people suffering from back pain, I recommend this one dynamic (flowing on the breath) asana above all others. If you would like instruction in this asana, it is best given in person or by reviewing the instructions in Structural Yoga Therapy. If you would like, I can give you general technique through this forum.
You do not state the specifics of your back issue. If this is a chronic condition, you may want to post to Mukunda or make arrangements to see him for a private session so that you can recieve specific and personalized instruction. Generally, back pain indicates a weakness or imbalance of the muscles which stabilize the spinal column. You may need to strenthen muscles in your bellyor your back, or to stretch muscles which are holding tension or are short in proportion to their antagonist (opposing muscle). Overall strengthening exercizes as found in a good general yoga class will help you to develop your general fitness level, decreasing the pain level, and to become more aware of the area of tension or weakness which is causing the back pain, empowering you to appropriate action to avoid it in the future.
Other comments from readers are welcomed, and Kiran is welcome to post a more specific question about his condition to Mukunda’s forum, or to browse the forum using the search function to find other posts about back pain.
Namaste,
Chandra
