Identifying common foot conditions

Infographic showing common foot conditions

Patients visit their pharmacy to seek advice on a variety of conditions affecting their feet. This visual guide for pharmacists and their teams illustrates some common foot conditions, and describes their key features, causes and treatment.

Musculoskeletal conditions

1. Arthritis

Symptoms of arthritis include pain and swelling in a joint or joints, stiffness and reduced range of movement and joint deformity

Causes: Osteoarthritis and inflammatory arthritis

Treatment: Refer to GP

The foot is involved in 80–90% of people with rheumatoid arthritis

2. Bunions

Bunions are bony deformities at the base of the big toe, which often cause it to point inwards

Causes: Family history, arthritis and poorly fitting shoes

Treatment: Offer bunion pads, insoles and painkillers if required. Refer to GP or podiatrist if pain interferes with walking. Surgery may be needed

23% of adults aged 18–65 years and 36% of elderly people aged over 65 years have bunions

Illustration of gout

3. Gout

Gout causes severe pain, swelling and stiffness in one or more joints, accompanied by red, shiny skin

Causes: Build-up of uric acid in the blood

Treatment: Refer to GP for treatment of acute attack with non-steroidal anti-inflammatory drugs, colchicine or corticosteroids. Lifestyle changes and prophylactic treatment may be required

Gout affects 2.5% of UK adults and is more common with increasing age, affecting 15% of men and 6% of women over the age of 75 years

4. Flat feet

Flat feet occur when there are no or low arches, causing possible pain in the feet, ankles, lower legs, knees, hips, or lower back

Causes: Hereditary, arthritis or an injury

Treatment: If painful, refer to GP or podiatrist for stretches and insoles

Flat feet may occur in up to 20% of adults, but many of these have no resulting symptoms

5. Plantar fasciitis

Plantar fasciitis causes heel pain when weight bearing that is worse in the morning but improves on walking

Causes: Inflammation of the plantar fascia caused by sudden or chronic damage

Treatment: Treatment includes rest, good footwear, heel pads, painkillers and exercises. Refer to GP or podiatrist if heel pain persists for several weeks. A steroid injection may be needed in severe cases

10% of people will develop plantar fasciitis at some time in their life

Skin, nail and soft tissue conditions

6. Corns and calluses

Corns are small circles of thick skin on the tops and sides of toes or on the soles of the feet and calluses are larger areas of rough, thickened, yellowish skin, often found on the balls of the feet

Causes: Excessive pressure or friction, often from poorly fitting shoes. Certain activities, for example, running

Treatment: Advise patient to remove pressure and apply rehydration cream, corn plasters, pads or salicylic acid products (but not for those with poor circulation or diabetes). If severe, refer to a podiatrist for skin removal

Corns affect between 13–48% of the population

Illustration of fungal nail infection

7. Fungal nail infection

Infected nails are thickened, distorted, white, black, yellow or green and sometimes surrounded by inflamed, painful skin

Causes: Fungal infection that thrives in moist, warm conditions. Commonly follows a fungal skin infection

Treatment: Offer antifungal nail laquer or solution. Refer patients who do not respond to topical treatment to a podiatrist or GP

Fungal nail infections affect 3–8% of the UK population

Illustration of foot with blisters

8. Blisters

Blisters are small fluid-filled pockets that form within the upper layers of skin

Causes: Poorly-fitting shoes, heat, chemicals or diseases such as chickenpox

Treatment: Advise patient not to burst the blister. Cover with plaster or gauze if needed. Refer to GP if infected

Heal naturally after 3 to 7 days

Illustration of foot with diabetic ulcer

9. Diabetic ulcer

A diabetic ulcer is a patch of broken down skin with visible underlying tissue

Causes: High or fluctuating blood sugar levels and poor circulation delay skin repair after minor injury. The peripheral neuropathy means the injury may go unnoticed

Treatment: Refer urgently to the local multidisciplinary diabetes team or GP — patient should be seen within 24 hours

10% of people with diabetes will develop a diabetic foot ulcer

Illustration of foot with verruca

10. Verrucas

Verrucas are areas of flat, rough skin with a cluster of black dots in the centre; approximately 1–10mm diameter. They can appear in pairs or groups

Causes: Human papilloma virus (HPV), transmitted by skin-to-skin contact or via contaminated surfaces

Treatment: Salicylic acid products can speed up the healing process; refer to a podiatrist if treatment is unsuccessful

Half of verrucas in children disappear on their own in a year and two-thirds resolve within two years, but they can take many years to resolve in adults

11. Athlete’s foot

Athlete’s foot causes dry, red, scaly, flaky, itchy and painful skin between the toes, starting with the little toe

Causes: Fungal infection that thrives in moist, warm conditions

Treatment: Advise patient to keep toes clean and dry, and apply antifungal cream, spray or powder. Refer to GP if no improvement after one week of treatment. Likely to recur even after successful treatment

Athlete’s foot is present in about 15% of the UK population

Illustration showing ingrown toenail

12. Ingrown toenail

Toenails can grow into the skin at the side of the nailbed, causing redness, inflammation and sometimes infection

Causes: Poorly fitting shoes or socks, badly trimmed nails, nail trauma, moist skin

Treatment: Advise patient to keep their feet clean and cut nails straight across. Offer an antiseptic cream or spray, but refer to GP or podiatrist if severely inflamed, bleeding or producing pus. Surgery may be required in severe cases

10,000 estimated new cases of ingrown toenails present in the UK each year

    Good article, straight to the point, very useful for a quick recap and update, the visual aspect of the article is useful for those who are not often facing patients.
