Bursitis is most commonly caused by repetitive motion or prolonged pressure on the joints, leading to inflammation of the bursa. Activities that involve frequent kneeling, bending, or lifting can irritate the bursa, especially in areas like the knees, elbows, or shoulders. Jobs or hobbies that require repeated motions, such as carpentry, gardening, or sports, are often associated with an increased risk of developing bursitis. In some cases, a sudden injury or trauma to the joint can also trigger inflammation of the bursa, leading to the onset of bursitis symptoms.

Other causes of Bursitis may include underlying medical conditions such as Rheumatoid Arthritis or Gout, which can increase inflammation in the joints and irritate the bursa. In rare cases, an infection can lead to septic bursitis, where bacteria invade the bursa, causing pain and swelling. Age is another factor, as bursae tend to become less resilient with aging, making them more susceptible to inflammation from daily wear and tear. By understanding the common causes of bursitis, individuals can take steps to avoid activities or situations that might increase their risk.

Joint pain is a common issue that can arise from a variety of causes, affecting people of all ages. One of the most frequent causes is arthritis, which involves inflammation of the joints. Osteoarthritis is the most common type, occurring when the cartilage that cushions the joints wears down over time, leading to pain and stiffness. Rheumatoid arthritis, an autoimmune disorder, is another common cause where the immune system attacks the synovial lining of the joints, leading to swelling, pain, and eventual joint deformity. Injuries, such as sprains, strains, and fractures, can also lead to joint pain, particularly if the joint has not healed properly or has been subjected to repeated stress over time.

Other causes of joint pain include bursitis (inflammation of the bursae, the fluid-filled sacs that cushion joints), tendinitis (inflammation of the tendons), and gout, a condition where uric acid crystals accumulate in the joint, causing sudden, severe pain. Infections in the joint, known as septic arthritis, can also lead to intense joint pain. Additionally, conditions such as fibromyalgia and lupus which affect the muscles and connective tissues can result in widespread joint pain. Understanding the underlying cause of joint pain is critical for developing an effective treatment plan.
