Been getting injections in both knees every 3 months for a while. Dr says I'll be having both knees replaced much sooner than later, probably starting next spring after snow goose season. 27 years of steel steps and gratings 5 or more stories high, concrete, and carrying too much weight has gotten both knees shot, left one is especially bad. My Dr won't do both knees at the same time.
I will say this; the injections I get provide INSTANT relief for as much as 2 months.
