Sorry to hear about your ailments. I had severe osteo-arthritis and hip necrosis. New hip, new knee over the last 18 months. I’m at the gym 3 days a week and ride a bike about 80 miles a week. I hope you find some relief. Pain sucks!
I'm medically disabled not from the feet but from the Inner Ear and sensory damage which makes me have upper torso seizures, Certain sounds trigger it as well as certain optic stimulation. I have to do things like shop late at night etc to avoid noise and crowds. On a positive note I'm at over 50% hearing loss now LOL.
I know some in here are protesting Medicare/Medicaid buying a scooter or chair. The math is simple on a scooter. Medicare pays $800-$1200 for a scooter that if treated right can last seven years and person retain independence, OR person can go in nursing home on Medicare/Medicaid at todays prices going about $30K for basic care. It's a no brainer. I'm against fraud though. I'll report it when I see it especially a vendor ripping consumer or Medicare/Medicaid off.
I believe Medicare/Medicaid cost can be lowered very significantly bu encouraging cheaper alternatives like home health care. In 28 years my wife has received less than a dozen home health visits total. I do procedures that in a nursing home would be LPN/RN skill levels. I believe in most cases person do better being taken care of at home as it's healthier. I say this as a former nursing home employee.
