Unless your illness or sickness is common or easily diagnosed, this doctor is of little to no help. I question his medical background and competency. He couldnt figure out was wrong with me so he tried to tell me that perhaps I was swallowing air. Long story short, I was not swallowing air and my conditions are serious enough that Ive had to stop working. If doctor McWilliams was out of his range of expertise then he shouldve recommended me to someone who could help instead of writing me off.
