Similarly to most other joint conditions, bursitis is most frequently caused by overuse or injury to the affected joint. Overuse of a joint leading to bursitis includes a minor but repetitive impact done onto the joint, or a sudden but more significant impact that has been made. Some activities that are known for aggravating the bursa and leading to inflammation include carpentry, gardening, golf, painting, shoveling, skiing, and raking. As we age, we become more at risk of developing bursitis as the tendons lose elasticity making them more susceptible to tearing, making it a common condition in those aged 40 and older. Other underlying health conditions can also increase the risk of developing bursitis, including arthritis, diabetes, gout, tendinitis, and thyroid disease. There is also a type of bursitis known as septic or infectious bursitis that is caused by indirect or direct infection and can be acute or chronic.
