Overview

Bunion
A bunion is a structural deformity in which the joint at the base of the big toe becomes displaced, causing the toe to angle toward the other toes and a prominent bump to develop on the side of the foot. Bunions may cause pain, swelling, redness, pressure from footwear, and difficulty walking or finding comfortable shoes.
Anal Fistula
An anal fistula is an abnormal tunnel that develops between the inside of the anus or rectum and the skin near the anus. It often develops after an infection or abscess in an anal gland. Symptoms may include persistent drainage, pain, swelling, irritation, or recurrent abscesses around the anus.

Diagnosis

Bunion
Diagnosis is usually based on examination of the foot and assessment of the position and movement of the big-toe joint. X-rays may be used to evaluate bone alignment and the severity of the deformity, particularly when symptoms are significant or surgery is being considered.
Anal Fistula
An anal fistula is diagnosed through a medical history and examination of the anus and surrounding skin. The healthcare professional may look for an external opening, drainage, swelling, or tenderness. A digital rectal examination may help identify the tract. Imaging such as MRI or ultrasound may be used when the fistula is complex, recurrent, or difficult to identify during examination.

Prevention

Bunion
Bunions cannot always be prevented, particularly when inherited foot structure contributes. Wearing comfortable footwear with adequate room for the toes, avoiding persistent pressure on the big-toe joint, maintaining appropriate foot mechanics, and addressing painful foot problems early may help reduce symptoms and progression.
Anal Fistula
Preventing anal fistula mainly involves reducing the risk of anal abscesses and treating infections promptly. People with inflammatory bowel disease should follow appropriate medical treatment and monitoring. Persistent pain, swelling, drainage, or recurrent abscesses around the anus should be evaluated by a healthcare professional rather than left untreated.

Risk Factors

Bunion
Risk factors include family history, inherited foot structure, abnormal foot mechanics, certain joint conditions, and repeated pressure on the big-toe joint. Footwear that places pressure on the toes may worsen discomfort or contribute to progression in susceptible feet. Having a risk factor does not necessarily mean that a person will develop the condition.
Anal Fistula
Risk factors include a previous anal abscess, inflammatory bowel disease such as Crohn disease, recurrent infections in the anal region, previous anal or rectal surgery, and conditions that interfere with normal healing or immunity. A history of an anal fistula also increases the likelihood of recurrence.
