I wake up wondering if I can play piano yet.  Lo and behold - I am able to do simple pieces such as Christmas carols.   More complex pieces - such as Chopin's Prelude in B Minor, which carries the melody in the left hand and uses the right hand for the haunting chord sequences - strain and hurt.  Piano requires lifting (the 4th finger onto black keys) and splaying the fingers.  I back off the harder pieces.

I am excited to see the progress.  On Tuesday, I could not do this.
