As I suffer from Vertigo a lot because of Meniere's disease, you might think about a job with a pool company. Like having a route with customers to check their chemicals and light cleaning. Pretty easy job with low stress as I do it for my pool all the time and know some people that have their own company and the employees can set their own hours and days that they work and still make pretty good money. Easy to learn and a very low impact job.
Internet work may be your best option. I am also a long sufferer of Vertigo and have found that Polysporin antibiotic Ear drops clear my problem in a few days. I use them as soon as I feel another bout coming on. Good luck.
