Serious question (not agere related)

What types of jobs would be suitable for someone whose knees are getting worse?

Backstory : over the past (I’d say) 6-7 months, my knees have been starting to hurt. The past week they have been getting so bad I’ve had to use my cane daily.

I need a wheelchair but to get a wheelchair I need a job. I also need to get a job so I can move out
