Vixen, sounds great.I am not a musician, nor am I a physician.
A number of years ago, (about 40), I identified a recurring problem, which was one of the forms of tendonitis/carpal tunnel injury.
What I my doctor did was to put a HARD plastic brace around my wrist so I couldn't move it in the direction which would cause the problem. After about 6 months of this, the problem went away. I assume the swelling of the muscle in the sheath had subsided. I try not to do the same thing again, but it may return. However, it is something to look at. This happened on my right hand, and as I am not sinister, I was worried the brace would interfere with normal work- Keyboarding, pen holding, etc.
If the doctor knows what range of movement you need, he can accomodate that when forming the brace.
Check with the specific doctor, rhynoplasty, I believe. (Otherwise known as Plastic Surgeons)
