Your symptoms match a wide variety of different medical conditions, including arthritis from wear and tear and physical injury like a dislocation or broken bone. If you are having trouble moving your joint, seek medical care immediately. If these symptoms are new and getting worse, it's best to have your doctor take a look at you. For any symptoms that concern you, or don't go away, your doctor is your best resource to help you get to the bottom of what's causing them.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Osteoarthritis is a type of arthritis caused by inflammation, breakdown, and eventual loss of cartilage in the joints. Also known as degenerative arthritis, osteoarthritis can be caused by aging, heredity, and injury from trauma or disease.
The anterior cruciate ligament helps to prevent the top and bottom of the knee from sliding back and forth. Symptoms and signs of a torn ACL include knee pain and swelling. Treatment of a torn ACL depends upon the health of the patient and the patient's expectations and willingness to undertake extensive physical therapy. Rehabilitation after surgical repair of an ACL tear may take more than nine months.
With a dislocated knee, the femur and shinbones are out of alignment. Severe pain, swelling, and joint deformity are symptoms and signs of a knee dislocation. Treatment typically involves reduction of the joint, surgery to repair torn ligaments, and immobilization.
Repetitive Motion Disorders (RMDs)
Repetitive motion disorders (RMDs) are muscular conditions that result from repeated motions. Carpal tunnel syndrome, trigger finger, bursitis, and tendonitis are types of RMDs. Symptoms and signs include pain, swelling, numbness, tingling, and loss of strength and flexibility. Treatment involves stopping the activity that's causing symptoms, adopting stretching and relaxation exercises, icing the affected area, and using pain relievers.
