Best Orthopedic Hospitals in Antalya

Knee crepitus can be from multiple causes. Painless crepitus can be ignored. So, I won't advice for crepitus knee treatment as such.. Crepitus from knee cap problems can be cured with hip and knee strengthening. Crepitus from cartilage irregularities or loose pieces often need minor keyhole surgery. Painful crepitus from arthritis is initially treated with physical therapy and surgery when therapy stops helping. 

You have patellofemoral pain syndrome. This condition causes pain around or under the knee cap, which can spread to the side of the knee. It's often due to overuse, weak muscles, or improper knee-cap positioning. Exercises to strengthen leg muscles and supportive sports shoes can help. A key part of treatment is avoiding activities that worsen the pain. 

You're having a hard time with back pain and arm pain. These are signs that may be brought on by factors such as bad posture, heavy bags, or sitting in an uncomfortable position for too long. Don't forget to take a break now and then, stretch, and do some light exercises like yoga which can help alleviate the ache. Additionally, you could use a hot water bottle or take a warm bath for relief.
