Hello,
At breakfast time, I like to shake my yogurt box against my solar plexus (just below the sternum) with the idea this will gently train those muscles to resist impact. No discomfort at all when I do it, but several hours later, after lunch time, I feel like someone hit me hard in the solar plexus radiating down either side of the belly button. No loss of breath, just the feeling of blunt force.
Does this ring any bells?
Thanks
Robin
