Preventing & Managing Residual Limb Complications

Healing after limb loss brings both physical and emotional challenges, and that's completely normal. Adjusting to your new life means learning different ways to approach your day-to-day routines, and some days will feel easier than others.

One of the most important steps you'll take is learning how to care for your residual limb. We know this might feel overwhelming at first, but proper care helps prevent complications that can slow healing or impact your ability to use a prosthetic comfortably.

While some issues may seem small or unimportant initially, they can become serious if not addressed early. The good news is that with proactive care and a little daily attention, you can prevent or catch most problems before they worsen.

Common Residual Limb Complications to Watch For

Skin Irritation and Breakdown

Friction from prosthetics, trapped moisture, or skipped hygiene routines can all lead to skin damage. This might sound like a lot to monitor, but many of our patients find that recognizing these signs becomes second nature over time.

Keep an eye out for these signs:

• Redness that doesn't go away after removing your prosthetic
• Blistering that seems to appear out of nowhere
• Open or weeping wounds that just won't heal

Left untreated, these can lead to infections or delays in prosthetic use, but with daily attention, most people avoid serious complications.

Infections Management

Any open wound can invite bacteria, and your residual limb is no different. While infections can be managed when identified early, they can be serious and deserve quick medical attention.

Watch for these warning signs:

• Swelling or warmth around the area that feels different from your usual healing sensations
• Pus or foul odor that seems unusual for your normal healing process
• Fever or feeling unwell overall

Neuroma Formation

When nerve endings heal in a tangled way, they can become painful, forming something called a neuroma.

You may experience:

• Sharp, stabbing pain
• Hypersensitivity to touch

Phantom Limb Pain

This feels like pain in the part of your limb that's no longer there. If you're experiencing this, know that it's real, it's normal, and it's treatable.

“Many people feel uncertain about phantom pain, wondering if it's "all in their head"—it's not,” explains Dr. Ajul Shah, a board-certified plastic and reconstructive surgeon and co-founder of ARMS.

Understanding phantom limb pain vs residual limb pain can be helpful: Phantom pain comes from the brain and nerves as they adjust to the change, while residual limb pain is from the remaining physical tissue. Both are valid, and both can be managed effectively.

Poor Prosthetic Fit & Pressure-Related Skin Issues

A prosthetic that fits poorly can cause friction, pressure points, or skin irritation on your residual limb. Upper extremity prosthetics should support comfort and function, not create ongoing pain or skin breakdown.

Risks include:

• Localized skin irritation or sores that affect prosthetic wear
• Discomfort that limits daily arm use or rehabilitation progress
• Delays in adapting to a prosthesis or assistive device

Prosthetic fit concerns are common and highly adjustable. If something feels off, early communication with your care team can prevent small issues from becoming larger setbacks.

How to Prevent Residual Limb Complications

Daily Skin Inspection & Hygiene

Daily skin checks might feel overwhelming at first, but they become second nature quickly. Check your residual limb every day, and if you need help seeing certain areas, don't hesitate to ask a family member or caregiver for support.

Here's what we recommend:

• Wash gently with mild soap, as if caring for sensitive skin
• Dry thoroughly, paying special attention to any creases or folds
• Apply unscented moisturizer to keep your skin healthy and resilient

Proper Prosthetic Fit & Use

Your prosthetic should feel comfortable and secure, not like something you're fighting against all day. If it doesn't feel right, trust your instincts.

Make sure to:

• See your prosthetist regularly for adjustments—they expect this and want to help you succeed
• Use socket liners for cushion and fit, designed to make your life more comfortable
• Speak up if something doesn't feel right, even if it seems minor

“Achieving the perfect fit often takes time and adjustments,” explains Dr. Shah. “This is part of the process, not a sign that something's wrong.”

Sweating & Moisture Management

Moisture management is especially important for upper extremity residual limbs, where skin folds, liners, or suspension systems can trap sweat during daily arm movement. Moisture buildup can lead to bacterial growth and skin irritation, but this is manageable with the right approach. Many of our patients find that moisture control becomes just another part of their day once they establish a routine.

Helpful tools include:

• Breathable liners and socks designed specifically for prosthetic users
• Residual limb-friendly antiperspirants that won't irritate your skin
• A check-in with your care team if issues persist

Stretching & Upper Extremity Residual Limb Exercises

Gentle, guided movements help keep your upper extremity flexible, improve circulation, and reduce stiffness as you heal. These exercises are tailored to your shoulder, elbow, and surrounding muscles and should always be guided by your rehabilitation team.

Benefits include:

• Maintaining range of motion for comfortable arm movement
• Supporting healthy tissue and circulation in the residual limb
• Preparing for upper extremity prosthetic use or adaptive daily activities
