40 day attempt

On the first of October I began the Meditation  for Intuitive Speaking and Applied Consciousness. On the 5th day, I noticed when I woke up, I was aching all over my body as if I had been run over by a truck. I was also nauseous.I assumed this to be because I was teaching Pilates now and doing my practice? Maybe??
Really, I was at a loss...
The next day I was better but there were residual effects. On the 8th day, in the middle of the afternoon, my ribs began to really hurt. It was difficult to walk, breathe and I had no idea what was going on. I left work early and came home to call some friends and ask what they thought of the practice that I was doing and possible repercussions. One thought that I had torn my rib tissue and to stop everything - not to do yoga,Pilates, period! The other friend agreed that I should discontinue the practice and see what happens.
So, I went to bed - not being able to lie down or breathe very well. I decided to take Arnica (30C). I did so at first every 15 minutes and then every 30 and gradually felt better and was able to sleep.
The next morning I was fine. In fact, I had a yoga which I taught with no problem.
But, I did not do the meditation and have not for several days now.
Yes, I was chanting Har and pumping my navel for over 11 minutes and the notes do explain that I will feel it in my rib cage...but this was incredible. 
I am writing about this for 2 reasons - to tell my story and to underscore that you may begin a journey to have it quickly go another way. I am of course disappointed that I had to stop but even more so - it is imperative to Listen to my body. Hopefully, I can begin a new 40 days soon.
