@ehBeth,
all is well !
potassium back to normal , physiotherapist made her climb the stairs (for a final test) and declared : "better than new !" .
she is home and doing very well - the pain of the last several months were pretty severe - a few weeks of "rest AND exercise" should put her back to her old-self again !
thx for all your nice thoughts and comments !
