I was sent for diagnostic testing. From Dr stapleton lvhn podiatry to get an emg with a NCS. The Dr that began the testing was Dr Joshua krassen DO. PHYSIATRIST. ON HOUSMAN Rd. In Allentown PA he began the testing. Didn't but tell me what was happening or what was going to happen. He just started the study. Once I asked him if he was going to use dirty equipment in me he said it doesn't go inside me. I said I need it cleaned. Then I question if he was a neurologist. He said no, he's a PHYSIATRIST. . He was offended. But once I began asking him questions about the testing he got fed up and said I'm sick of you people and your bullshit. I said what people? Black people? Then he walked out said he's done. And my testing was never competed. The nurses gave me some water and said I won't he charged. His assistant verified he was beligerant
