I am sorry to hear you got CTS. Surely you have been thinking about what caused it in the first place (my guess, not knowing you, is that a combination of overpractice, tense playing, dual-pull movements in your technique and a repertoire heavy on the loud and fast stuff may be involved).
If I would you, I would try to find in my heart the patience and love to spend some time with Haydn and Mozart (never wasted time) and look into the culture of healthy playing, along the lines of Taubman, Golandsky, Matthay, etc.

Best wishes, good luck, and put the Paganini-Brahms and the Prokofiev war sonatas down for a while.
Also, a letter to Leon Fleisher would not be out of place.
