On day 4 of his drug trafficking trial in Green Bay, former Manitowoc Dr. Charles Szyman took the witness stand. He stated, “When people speak of pain and the treatment of pain, we talk about the complications of treating the pain, but we rarely speak of the complications of not treating the pain.” By the end of his practice at Holy Family Memorial, Szyman said he was seeing 350 to 400 patients and only a small percentage were on what he called high-dose opioid therapy. He said he first encountered the therapy, using high dosages of opioids to treat non-malignant chronic pain, in a seminar in the early 1990s and it seemed practical to him. “To me, it made sense,” Szyman said. “Why does a human-being have to suffer just because they don’t have cancer?” Both sides are expected to make their closing statements today, followed by jury deliberation.
