Pain is no fun, but a great communication tool from your body. It definitely lets us know when something isn’t working. I like what Charliedharma said:
Your shoulders are precious look after them.
Yoga, when done in optimal alignment, can be enormously healing. When done misaligned, yoga can be one of the most risky things you can do.
The advice you’ve received about being patient with yourself, doing physio, and finding a yoga therapist are good. I offer you this perspective to add to your considerations:
Personally, as an Anusara-Inspired yoga therapist, I wouldn’t advise you to stop doing yoga as long as you can do it in alignment. The trouble comes when you don’t know or haven’t been taught what this is.
Learning how to align the shoulders can bring you out of pain and into freedom very quickly. Once you understand what optimal alignment is and how to do it, you apply it to your practice and use poses that bear as much weight as possible IN ALIGNMENT. This strengthens the muscles around the area of injury in a healing pattern.
For example, if you can’t quite maintain the alignment in Down Dog, you come to your hands and knees with arms out further in front at an angle like Down Dog so you can work the alignment without as much weight. If that is too much you continue to modify until you can stay in alignment.
The alignment of Anusara yoga has been life changing for so many people. I’ve helped people in chronic pain to find total freedom in a matter of minutes by teaching them the principles of alignment and how to apply them to their lives. I know you said there isn’t a qualified teacher in your area. You may want to think about traveling to one if it’s reasonable.
If you are able (and if it resonates with you), try to find a certified Anusara yoga teacher to help you understand the principles of alignment from this school of yoga. Their teacher directory is here: http://www.anusara.com/index.php?option=com_contactmanager&view=teachers&layout=certified&Itemid=128
Also, if there isn’t anyone close to you, Martin Kirk does yoga therapy online via Skype using video. This may also be an option for you. http://www.kirkyoga.com/private.html
Finally, if you’re interested in learning more about the approach of this yoga, including the philosophy, meditations, and some alignment, I invite you to try my free online offering.
Lots of links there, I know. I wish I could teleport myself or another skilled teacher there to help you. May your path lead you to radiant, beautiful health.
Blessings,
