Because knees are prone to wear and tear from regular use, it’s not uncommon for people to experience minor aches and pains in their knees on a regular basis. These pains may go away on their own, but not always. If your knee pain doesn’t go away or is disrupting your life in any way, you should not ignore it. This is especially true if you’re experiencing other symptoms, such as popping noises, instability, swelling, movement within the knee, redness, or warmth. All of these symptoms can indicate a condition or injury that requires medical care.
