I got my first and only chiropractic adjustment, the doctor twisted and popped my back. It immediately went into spasm and he sent me home with a belt. The next day they called, My back was sore but hip was better. The third day I woke up nearly paralized with back/hip pain, unable to walk. I went to the ER and was administered some anti-inflammatory drugs, 8 hours later they began to work. I never contacted the Chiro again, I had no time and wanted to move on. The place of business had come under scrutiny in the news for other issues and I commented online. I shared my experience, telling what happened and that I would never visit a chiro again. The owner/doctor sent me a letter claiming if I do not apologize and remove the post, he will sue. Can he win?
