  https://www.yalemedicine.org/conditions/bursitis

  Bursitis is the term used to describe inflammation or irritation of one or more fluid-filled sacs (known as bursae) located at joint and muscle interfaces. […] There are several reasons why a person may develop bursitis, including: […] Repetitive motions or putting too much pressure on a joint may lead to bursae inflammation. […] Chronic bursitis, often due to joint overuse over time, may not cause pain; the effects on the joint are ongoing, which enables the bursae to adjust to their larger size. […] The type of treatment also depends on the cause of bursitis. […] If bursitis is due to repetitive motion, overuse, or prolonged pressure on joints and muscles, doctors can show patients how to change their behaviors to alleviate the problem. […] When bursitis is caused by a bacterial infection, doctors will prescribe antibiotics. […] People may also experience recurrences if their bursitis is caused by another medical condition, such as untreated gout, osteoarthritis, or rheumatoid arthritis.

  The underlying causes of hip bursitis vary widely, ranging from an obvious trauma to a systemic disease such as gout. […] The most common causes and risk factors include: […] Hip bursitis can be caused by repetitive mini-traumas to the bursa. […] Hip bursitis is more likely to develop in people who are already prone to joint pain from other inflammatory conditions, such as rheumatoid arthritis and gout. […] Being overweight can affect gait and/or put excess strain on the hip joint, increasing the risk for hip bursitis. […] Certain physical conditions, such as scoliosis, low back problems, and differences in leg length, can alter the hips biomechanics. […] Hip bursae and other soft tissue can become irritated by bone spurs, also called osteophytes, and calcium deposits, which are small collections of calcium that are often small and soft but can grow and harden over time.

• #1 Septic Bursitis – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK470331/

  Inoculating the bursa with infections bacteria causes septic bursitis. This happens most often from micro-trauma or direct puncture of the overlying skin causing subsequent infection. Contiguous spread of overlying cellulitis of the skin is also a common cause of superficial septic bursitis. In 80% to 90% of cases, Staphylococcus aureus is the most common organism in acute septic bursitis and Streptococcus species being the next. Other organisms include Escherichia coli, Enterococcus, Pseudomonas aeruginosa, and coagulase-negative staphylococci. Chronic, infectious bursitis is likely due to atypical mycobacteria and fungi and should warrant prompt evaluation for systemic infection. […] Septic (or infectious) bursitis occurs when infection from either direct inoculation (usually superficial bursa) or hematogenous or direct spread from other sites (deep bursa involvement) causes inflammatory bursitis.

  https://www.healthline.com/health/bursitis

  Bursitis can also be classified by what causes the inflammation: […] Aseptic (nonseptic or noninfectious) bursitis is usually caused by repeated minor trauma to the joint area or strain injury. […] The most common causes of bursitis are injuries or damage to your bursae. Damage may trigger pain, swelling, and redness in the affected area. […] However, causes tend to be different for each type of bursitis. […] Septic (infectious) bursitis occurs when the bursa becomes inflamed due to an infection from bacteria. This usually happens when bacteria are directly introduced into the bursa through a wound in the surrounding skin. […] Skin infections, such as cellulitis, may lead to septic bursitis. Blood or joint infections can also spread to the bursa and cause septic bursitis.

• #1 Common Superficial Bursitis | AAFP

  https://www.aafp.org/pubs/afp/issues/2017/0215/p224.html

  Septic superficial bursitis is also uncommon. It occurs more often in the olecranon and prepatellar bursae than in other superficial bursae. It usually arises from infection in nearby tissues, such as cellulitis, because of direct inoculation from trauma, or iatrogenically as a result of an attempt to aspirate an enlarged bursa. […] Up to one-half of septic bursitis cases occur in patients with chronic systemic conditions such as diabetes mellitus and chronic kidney disease. Patients with alcoholism and those who are immunocompromised are also at risk. […] Joint crystal disease, most commonly gout (and rarely pseudogout), can cause a chronic inflammatory superficial bursitis. Superficial bursae are not typical locations for an acute gouty attack, but the olecranon and prepatellar bursae are most often affected when it does occur.
