There are a limited number of GPs in Civic, the closest, largest and conventional of these seems to be eternally booked solid a week in advance so on a couple of occasions I've ended up with a Chinese doctor near by.
He thinks the knee is a strained ligament which confirmed my plans to take it easy for a week or so and also recommended voltaren gel and acupuncture.
There was some relief at the end of the session but it faded fairly quickly. I have another appointment on Thursday and we'll see if it helps some more then.
Also too early to tell if the voltaren is helping.
