I think you need a second opinion. I have severe osteo arthritis in both knees. I also worked in the hospitality industry as a cook. I'm presently trying to rid myself of 50 pounds to be able to get both knees joints replaced. I'm 54 years old. I lost my job due to my knees, please get a second opinion.
You need to see a rhuematologist and another orthopod. Do not just see a family doctor. You need to keep that joint moving, range of motion is so important and there other drugs out there that are better for inflammation. Naproxen is brutal on your stomach, trust me on that one.
Do not take a cortizone injection. Please get a second opinion, it is your right. Do not fool with arthritis, please get it checked out further. Take care and I wish you the very best.View Thread
