Yes definately go in and speak to him. Him not returning your phone calls or your physicians is highly unprofessional. I would have issues seeing him again based on what you have shared.
My surgery is scheduled for Nov 10th. I am in North Carolina. Been doing my research and talking to people who have sleeved before me. A friend of mine had hers 2 weeks ago, so I have been getting much info from her. She has been great.
