Hello, I m a 60 yr old woman experiencing pain in my left knee joint. It seems to come and go, but I work in long term care, and it seems to flare up more when I m working. I have been wrapping it with an ace bandage, icing it and been taking acetaminophen. I m wondering at what point I should go to a MD. I can t afford to be pff work, so I m afraid of what a MD might find.
