I used to get tendonitis all the time as a teenager. The presciption ranged from strapping up my arm to anti-inflammatories.

I discovered my own cure. I went from playing a classical nylon String guitar with a wide neck to a steel string. Tendonitis gone.

Came back a little while ago when I got a gig playing Spanish-style guitar and had to use the nylon string again. (Especially those barre chords!). It felt kind of weird having that old problem come back after years.

Unfortunately, I have to live with the fact that I am not able to play classical guitar. At least the steel string has no bad effects.

I took lessons in jazz improv for a while. We had a fantastic teacher who taught us very little about what notes to play but loads of other things: the Alexander technique; holding the instrument; frame of mind; practice time. At first I thought it was all a bit hippy-peace-and-love, but it HAS improved my musicality and outlook. I'd recommend Alexander technique to muso.

Hope you're feeling better soon.
