I did apply cold compress lavishly, and that really helped. Heat actually, while it also feels like relief, was not recommended by the doctor in a case of inflammation. Thanks for the concern Andreas. I'm all better now and back to normal (but can still feel it when I push it too hard). I intend to record the Scriabin LH Prelude+Nocturne and the Brahms-Bach LH chaconne when my grand is tuned. Maybe also the Bartok LH Etude. These are the pieces I worked on while disposed.
