Well managed so far this am. Cat feeding last night was fine, though had to do 3 trips (wet, water & dry) rather than 1. Tea making no problem, proper cooking just won't happen. I can use the hand on my dominant side, just not allowed to move the shoulder so hand is only at my belly button. Packing away can be done spread over time.
DSis lives close, but works shifts plus I think she's done plenty for me already. I will be able to call on her if absolutely necessary but will avoid if poss.
Next big test is it's rubbish day tomorrow, so full litter change day today!
