Yesterday I was mopping the floor with water and detergent. I was bare-footed and wanted to pull the table. The table is heavy as it has a marble top. So I started to pull it towards me and unexpectedly I slipped and my bottom and the last vertebra hit the floor so hard. It was so painful and soon I forgot all about the pain and continued to clean. When I went to my yoga class an hour later, I was exercising and when it was time to do the part that we do while sitting on the floor it was so painful to sit down. The area was a little sore after the yoga. I am taking anti-inflammatory and I hope it is not serious. I have not gone out today (Sunday). I am working at home in order to rest it.  I was thinking about the fall last night and said: oh my God. If I am not careful, a trauma like this can paralyze me, God forbid.
