Physios study for at least four years to make the exercises as boring as possible. Stick with them - they work in the end.
If your injury is just tissue or muscle, you probably want a physio - not a doctor. (If it's serious enough the physio will refer you to a specialist).
In Jozi I know of at least two physios who climb (or climbers who pay for their climbing with physio practices, depending on your point of view):
- Mark Seuring (firstname.lastname@example.org
- Andrew Tyler (+27 83 707 2595)
I'm sure there are many more. I haven't been to either Mark or Andrew, so can't comment on their skills.
Lou-Ann Rivett is a well known sports physio in Jozi. She doesn't climb, but as a former Springbok triathlete I think she'll understand your injury. Her rooms are in Randburg - look her up in the telephone book.
Hope you recover quickly
