I had trigger thumb - a painful condition where the joints in my thumb locked up. Dr. Robert Leak had surgically helped my brother-in-law with carpal tunnel syndrome, so I went to him. Boy did he take care of it. He injected my thumb; my thumb is fine. Thanks, Dr. Leak and team! I can't tell you all how much I appreciated the relief. The pain was terrible, and the writing was very, very difficult.
