[|Human|] i have woken up today with quite severe knee pain. I was flying yesturday on a 7 hour flight and today am in quite a lot of pain in my right knee. I am struggling to walk or climb stairs and feel like my leg will collapse under me at any point. Can you help. I suffered with growing pains in my knees when i was a teenager. I exercise although not too much as if i run too much without at least a days break between then my knees also hurt. I sometimes hear a cracking noise from my knees when i stand after sitting down although this is not painful
[|AI|]  Hi, Knee pain could be due to any ligament, tendon, meniscus injury or autoimmune / inflammatory condition like arthritis etc. But the one with cracking or popping sounds in or around the knee joints could be a sign of emerging osteoarthritis. With this feature, age, gender, weight should also be considered as it might increase the risk of arthritis. I advise you to:- Do X-ray both knees-Analgesics like Tab. Ibuprofen or Diclofenac + Ice pack + Regular exercises- Intra-articular glucocorticoids if pain and swelling persists even after using analgesics- Charon Chat Doctor.  Hope I have answered your question. Let me know if I can assist you further.
