A knotted up sensation coupled with watery BMs is a possible sign of a partial blockage.  If these symptoms persist I would call Dr. and/or go to ER.  I had blockages in the weeks after takedown - you are very prone due to possible adhesions and scar tissue and/or residual surgical swelling.  I don't know what you have been doing diet-wise but I would not be eating big meals.  Take it easy until you are a couple months out.  People start feeling good and they get aggressive with their diet - and then stuff happens.  Been there and done that.

went to er was there 2 hours was 35 people ahead of me still so i left feeling little better dr out of town till wed haven't taken any comital oh imodium today just drinking water and had a yogurt not sure what to do
