I made a scheduled trip to the dentist to have an old filing replaced. They used a nerve pain blocker on my upper jaw and things were going well. I noticed my hand tremor was more pronounced while I was in the dental chair. It was completed and I sat up. I felt more unbalanced and my tremor was much worse. I also noticed my whole body begin to shake. I felt as though I was slow to react and off meds for sure. Any information on pain blockers used by dentists and people with PD?
