What Are Some Causes of Inflamed Toes?

Abscesses, blisters, bunions, bursitis, cellulitis and bone infections are all common causes of toe inflammation. Different types of arthritis are also known to cause toe swelling, according to Healthgrades.

An abscess is a collection of pus underneath the skin caused by an infection or the invasion of a foreign object. Bursitis is the medical term for inflammation of a bursa sac, which is a cushion for joints, explains Healthgrades. Cellulitis is a type of skin infection that also affects underlying soft tissue.

Osteoarthritis and rheumatoid arthritis are commonly associated with toe swelling. Osteoarthritis is a condition in which the cartilage in the joints breaks down, and rheumatoid arthritis is a chronic autoimmune disease that inflames the joints, notes Healthgrades.

Osteoarthritis commonly develops with age, but joint injuries and obesity are also contributing factors in many cases. This type of arthritis commonly affects the feet as well as the knees, hips and spine, reports WebMD. Left untreated, rheumatoid arthritis can cause serious damage to the joints. Doctors are unsure of what causes rheumatoid arthritis as of 2016. Some speculate that the immune system is confused after fighting off a serious infection and starts to attack other systems in the body, such as the joints.
