Mr. Lee, 38, noticed swelling in his left big toe over 20 years ago. But at the time, I didn't know I had gout, and my family thought it was rheumatism.

These subcutaneous lumps are actually tophi.

Knee pain is a common complaint that can affect people of all ages, from high-school athletes to active seniors. Whether it's a nagging ache, a sharp pain during activity, or a constant discomfort, knee pain can significantly impact your daily life.
