My knees turn red and hot when i stand for more than five minutes. they don't always hurt. should i worry about this? arthritis runs in my family.

Knee arthritis: Knee arthritis certainly runs in families. The 2 main types of arthritis are osteoarthritis (wearing of the joint) and inflammatory arthritis (multiple painful, swollen joints with deformity). If both knees swell and become red in 5 minutes, you should be tested for rheumatoid arthritis. Additionally, knee xrays are needed. These tests will determine if, and what type of arthritis you may have

Arthritis: Redness, warmth and pain are symptoms of arthritis. If they are short lived, rheumatoid arthritis is not likely. Keep a diary of your symptoms over a week or two and discuss with your primary care doctor. If symptoms are persistent, consider making an appointment to see a rheumatologist.
