Bursitis is normally caused by overuse of the joints, tendons, or muscles that are near the bursa. However, it can also be caused by injury or trauma, bacterial infections of the bursa, and Rheumatoid Arthritis and Gout.
Bursitis can be mistaken for Osteoarthritis as both ailments have the same symptoms. The only difference is the actual cause of the symptoms. This form of Arthritis happens when the protective cartilage thins or disintegrates causing bone-on-bone contact. It can also cause a decreased range of motion. Another major symptom that may point to Osteoarthritis instead of bursitis is crunching and popping of the hip. This is an indication that there is bone-on-bone friction.
Symptoms of Bursitis include redness, pain, swelling, and stiffness in the knees, shoulders, elbows, and hips.
