Asking for some advice about salah and wudu during recovery...

Salaam everyone. I'm having shoulder surgery next month and afterwards I'll need to be in a sling for about six weeks, and I have to be really careful with how I move. I'm getting a bit anxious thinking about how to manage my daily prayers and wudu in this situation. Performing wudu properly seems really tricky with one arm basically out of action. I know I can pray sitting down, which helps, but the whole process of getting ready for salah is what's worrying me, especially for Fajr. If anyone has been through something similar or has any practical tips, I would be so, so grateful. Jazakumullahu Khayran.
