He was very kind and understanding. He was doing a procedure on my leg and I freaked and he stopped. He is one of a kind for a Dr. He said he would try and figure out how to do this procedure in another way so I dont freak again. I told him " they need to get Nitrus in their office" that helps tremendously, or at least for me it does. The previous Trama I have gone thru has caused alot of problems.
