Comments: First, I visited a head of columbia orthopedics and have not received meaningful help. An oral immunosuppressant drug was suggested. Immunosuppressants increase a risk of cancer. Then I visited Dr. John. Dr. John made an injection into a knee and suggested that it may help for a few months or even longer. I was sceptical. Then I have not had symptoms for ~3 years. Three years later I found Dr John online again. We are working on the second knee now.
