I have front lower leg pain including knee and ankle when sitting with leg slightly elevated such as when driving my car . It goes away when standing. ( I had the cartilage removed from knee in 1952, but this is a new problem.) Thank you for your ideas.
Hello, It could be an early sign of arthritis or can be due to ligament injury. You can consult an orthopedician and get an MRI scan done to look for any possible ligament or tendon injury. As of  now, you can take analgesics like Ibuprofen or Diclofenac for pain. Hope I have answered your query. Let me know if I can assist you further.
