[|Human|] Hi i have knee pain in my left knee for the past month at night time and when resting my knee during the day. They also crack every time i bend down. Is there something I should be worried about? I m also and active 18 yr old who likes to play sports.
[|AI|]  Hello, As you are 18 and facing pain in knee and cracking sounds most times, I think you should try strengthening the muscles of the knee to maintain the joint space.  As the joint space reduces there is friction of the bones leading to inflammation and the pain along with cracking sounds. Also, there might be some calcium and vitamin D deficiency, so having it checked and taking a medical prescription for the same will be of additional benefits. Research studies have shown in recent times most people in there 10-20 years of age are facing difficulty with low calcium and vitamin D levels. With an oral supplement and exercise of the same have some positive results. Hope I have answered your query. Let me know if I can assist you further. Take care Jay In Chat Doctor.
