Hi Janayah
Here are a few ideas for you 😉
I am wondering if this strange sensation you are talking could possibly be muscle pain and the stretching of your connective tissue as you learn to breathe more fully and your ribcage and your lungs are expanding more.
Does the ‘digging in’ of your ribs feel like a tightness, or a resistance of your ribcage that is not quite ready to surrender to your growing lungs?
Just a thought. How easily are you adapting to using your diaphragm and your abdomen when you breathe? You may find my new instructional video helpful in deconstructing breathing technique. Here’s the link: Effective breathing in hot yoga
Another thought: I don’t know how flexible you are, but is it possible that when you are in your big half moon side bends or your back bend that you are feeling your ribs digging in. If this is the case then we can talk about the way you can set up to create space in the poses that this can happen.
Namaste
Gabrielle 🙂
