My visit was for X-ray and consult on it. This leads to MRI, but even before needed MRI, she was suggesting surgery immediately. Even when asked, she didn’t suggest any care between now & treatment, not even if or how often to ice. Nothing. I don’t know how to care for injury during the 2 weeks until doctor consult on diagnosis of injury.
