Many individuals with rheumatoid arthritis struggle to manage associated foot pain. There is hope for relief from the pain and inflammation. From massages to surgery, a variety of options are available to alleviate discomfort. Continue reading below to learn more about what you can do to manage foot pain related to rheumatoid arthritis.
Blogger Cathy Kramer, now 53, found out she had rheumatoid arthritis (RA) in 2004. Painful feet have been a hallmark of RA for her from the start. “The joints in my feet were among the first to be affected — X-rays have shown some [joint] erosion. Even during my best days, my feet have always been a sore point,” Kramer says. Erosion refers to the wearing away of cartilage and bone in the joint. It’s caused by inflammation within the joint lining.
Kramer is not alone. About 90 percent of people with rheumatoid arthritis have some kind of foot pain, according to the American Orthopedic Foot & Ankle Society, which makes walking difficult and restricts daily activities. And yet, the researchers warned, not enough attention is paid to foot care. Rheumatoid arthritis can attack any of the foot’s joints, leaving them inflamed and painful.
Signs and Symptoms of RA-Related Foot and Ankle Pain
You might find that pain is affecting both your feet in the same locations. For some people, the ankles hurt the most and might appear swollen. You might feel other symptoms as well.
“Patients complain of pain in the toe joints, ligaments, or ankles mainly upon arising from bed. It is associated with joint swelling, redness, and warmth. Rheumatoid nodules can also develop. This can lead to joint deformities and widening of the forefoot, necessitating an increase in shoe size,” explains a rheumatologist at the Louis Stokes Cleveland Veterans’ Administration Medical Center in Ohio. The doctor adds that the pain and stiffness may be worse in the morning, forcing you to get up an hour or more early in order to prepare yourself for the day.
A study published in the July 2018 issue of Journal of Foot and Ankle Research compiled the recommendations of a panel of 24 medical professionals and patients to diagnose and treat foot problems related to RA. Based on the foot issues, treatments include medication, exercise therapy, a variety of shoes, braces, and orthotics, or surgery.
Your rheumatologist can also prescribe you medications, called disease-modifying anti-rheumatic drugs (DMARDs), that control the inflammation and prevent joint damage, notes the rheumatologist.
Joint Pain and Inflammation With Rheumatoid Arthritis
Just as with joints in other parts of the body, rheumatoid arthritis causes inflammation of the lining (the synovium) of the joints in the foot, according to the American Academy of Orthopaedic Surgeons (AAOS).
“Inflamed joints can be eroded and leave a scarred joint. The ball of the foot then becomes a rough, bumpy bone,” says a professor of internal medicine in the division of rheumatology at the University of Kentucky in Lexington. “Active inflammation and eroded, damaged bones cause pain.”
Painful Foot Problems Related to RA
One of the targets of this inflammation is the joint capsule, which normally acts like a sleeve, protecting the joint by adding stability to it.
Some of the deformities related to rheumatoid arthritis include:
- Bunions (Hallux Valgus) – This is an enlargement of the joint at the base of the big or little toe.
- Hammertoe – Hammertoes and claw toes occur when the toes are permanently bent under.
- Bursitis – Fluid-filled sacs (called bursae) develop under the ball of the foot and may become inflamed and swollen. They commonly occur along with bunions.
- Charcot Arthropathy – Also Called Charcot Foot and Ankle If one or more joints in the ankle or foot become severely damaged. The foot may collapse, resulting in a deformity called Charcot arthropathy.
- Plantar Fasciitis – Inflammation of the plantar fascia in the sole of the foot causes pain under the heel.
- Rheumatoid Nodules – These firm lumps, which are the size of a pea, occur where pressure is put on the foot, like the soles and the big toe joints.
- Valgus Heel – Joint damage may cause the heel to push outward, which results in valgus heel.
Rheumatoid Arthritis May Lead to Other Foot and Ankle Issues
Another foot problem experienced by people with RA is nerve pain. Peripheral nerve pain in the foot can cause burning, tingling, and tenderness. Continued pressure on the medial side of the foot can then result in nerve entrapment, or tarsal tunnel syndrome.
Foot pain often occurs in the joints or ball of the foot. In fact, for about 20 percent of people with RA, foot and ankle issues are the first symptom of rheumatoid arthritis, according to AAOS.
Manage the Rheumatic Disease, Manage the Foot Pain
Surgery is often needed to alleviate the pain associated with bunions, hammertoes, and nodules, according to AAOS. Foot surgery may involve resetting the bones or fusing joints to correct the position of bones and joints.
Local steroid injections are particularly beneficial for inflamed joints and plantar fasciitis. But before you schedule surgery or an office visit for injections, you might try non-invasive approaches such as braces, or choose shoes or inserts designed to support your feet, AAOS recommends.
Uncontrolled inflammation leads to joint bone erosions and other damage, which leads to foot deformities, a doctor claims. “Early use of the newer and much more effective remittive drugs to lesson or eliminate inflammation is key to preventing bone damage and resulting deformities,” says a professor in the division of rheumatology at the University of Kentucky in Lexington.
What’s the Right Footwear When You Have RA?
Narrow-toed or pointy-toed shoes, as well as heels, are bad for the foot as they cause the wearer to put pressure on the ball of the foot and can cause marked deformities. An oxford-type shoe with a low heel, wide toe, and high ceiling that will not rub the foot is best.”
Good arch support will help distribute the weight evenly on the entire foot, and orthotics — special devices put into the shoe — can alleviate foot pain caused by rheumatoid arthritis and possibly prevent deformities in the foot, a doctor adds.
8 Tips to Relieve or Avoid Foot Pain
In addition to the right footwear, pain medications, and surgery, there are things you can do to reduce foot pain from rheumatoid arthritis:
- Change your exercise of choice. It’s important to exercise to keep your joints mobile, but choosing exercises like swimming that don’t put more pressure on your feet can help avoid additional foot pain. Kramer says she enjoys bicycling when she can.
- Work with a podiatrist. A rheumatologist explains that a foot specialist might be able to help you find the best orthotics for your shoes, and also help your feet feel more comfortable by caring for calluses and other irritations.
- Buy shoes you will actually wear. People don’t always wear the special shoes they’ve been prescribed, for reasons such as dissatisfaction with fit, comfort, or style, a doctor claims. Try out new shoes by wearing them in a variety of situations and at a variety of times, recommends Kramer, who orders her shoes online and returns them if they don’t meet her standards.
- Listen to your feet. Kramer says she has learned to choose what shoes she’ll wear each day by being better in tune with her feet. “I don’t have a ton of shoes, but what [shoes] I have are quality and allow me to listen to what my feet have to say,” she explains. For example, on some days her feet need lots of support, while on others, they need room to breathe.
- Take the load off. Avoid standing all day. Try to alternate the activities you do so that you’re sitting part of the day, and standing at other times.
- Lose weight. The more you weigh, the greater your risk of foot joint pain with or without rheumatoid arthritis, finds research published in Arthritis Care & Research. Aim for a healthy body weight.
- Check your feet daily for problems. Cover blisters or minor cuts and scrapes as soon as you get them; see your doctor if they haven’t healed in two or three days.
- Take a warm foot bath or get a massage. The Arthritis Foundation recommends trying hot or cold therapies as needed to ease aching joints. Kramer swears by a daily foot massage that she gives herself with coconut oil.
The best way to manage your foot pain is by keeping your rheumatoid arthritis under control. If you do, you can keep your feet happy.
