Rash Before Surgery: When to Call Your Surgeon

If you notice a rash before surgery, call your orthopedic team promptly, even if it seems minor. Your surgeon needs to know about skin changes before a hip, knee, shoulder, or other joint procedure.

A rash can have many causes, and its appearance alone doesn't tell you what it means for your operation. Early communication gives your care team time to review the change and advise you on the next step.

Key Takeaways

• Report a new or changing rash anywhere on your body, especially near the planned incision.
• Call your surgical team as soon as you notice the change. If surgery is near, call rather than waiting for an appointment.
• Share where the rash is, when it started, and whether you have other symptoms.
• Seek emergency care for severe symptoms such as trouble breathing, fainting, or sudden confusion.
• Keep following your existing medication and surgery instructions unless your care team tells you otherwise.

Why a Rash Before Surgery Matters

Your skin is part of the body's barrier against bacteria. During joint surgery, the surgeon makes an incision through that barrier, so the condition of the surrounding skin is important.

Skin health is part of surgical planning

Before an operation, we review more than the joint itself. Skin changes, recent illness, medications, and medical conditions can all be relevant to the surgical plan.

For example, tell us about an open sore or drainage as well as a rash. The location matters, too. A spot close to the planned incision gives your surgeon different information than irritation on another part of your body.

Joint replacement involves an implant

If an infection develops around an artificial joint, it can be difficult to manage. For that reason, your team pays attention to possible sources of infection before surgery and to the condition of your skin.

Your surgeon will consider your complete health history rather than making a decision based on a description alone. Our guide to pre-surgery testing and clearance for hip replacement covers the broader health review.

Skin Changes to Report Before Joint Surgery

You don't need to identify the cause of a skin change before calling. Describe what you see and how it feels. Even if you have had a similar problem in the past, let your team know about a new episode or a change in its usual pattern.

Changes near the planned incision

Pay particular attention to the area around the joint scheduled for surgery. Report a patch of redness, bumps, blisters, scaling, or irritated skin. Also mention cracks, cuts, scrapes, sores, or areas that are wet or draining.

For hip surgery, tell the team about changes on the hip or nearby skin. Before knee or shoulder surgery, report changes around the planned surgical area. If you aren't sure where the incision will be, describe the location as clearly as you can.

Changes elsewhere on your body

A skin problem doesn't have to be beside the joint to be worth reporting. Tell your team about changes on your feet, lower legs, hands, trunk, or skin folds, as well as any widespread rash.

Mention insect bites, wounds, or a chronic skin condition if the affected area has changed. If you have a foot wound or a history of recurring skin infections, include that information in your preoperative review.

When to Call and When to Seek Emergency Care

A prompt call is the right starting point for a new skin change before joint surgery. You don't have to decide whether the change is serious before contacting us.

Call your surgical team promptly

Call as soon as you notice a rash or other change. If you have a fever, chills, feel unwell, or have noticed drainage, tell the person who takes your call. The same applies if the area has changed since you first noticed it.

When surgery is the next day or scheduled for that morning, use the phone rather than relying only on a message. Follow the after-hours instructions if the office is closed, and tell the team your surgery date when you call.

Get emergency help for severe symptoms

Call 911 or seek emergency medical care for severe trouble breathing, swelling of the tongue or throat, fainting, or sudden confusion. These symptoms need immediate attention. Don't wait for an office callback.

Once you're receiving care and can do so safely, let your surgical team know what happened. The clinicians treating you can also help communicate with the team.

What to Tell Your Surgeon About the Rash

A clear description helps your team decide what information or examination they need. It's fine if you don't know every detail. Call with what you know rather than waiting until you can answer every question.

Describe the location and changes

Say where the area is and which side of your body it affects. Mention its approximate size and whether it's a single patch, several spots, or a wider area.

Tell the team when you first noticed it and whether it has changed. Useful details include itching, tenderness, warmth, swelling, broken skin, blisters, or drainage. If the area looks different in person than in a photo, say so.

Include the rest of your health history

Share any fever, chills, or other symptoms you've noticed. If you have a thermometer reading, give the number and when you took it.

Mention a previous skin condition, recent infection, or recent antibiotic use. Also tell the team about medicines or products you've used on the area, including anything available without a prescription. Bring your medication list to any visit, since the drug name and dose are more useful than a general description.

How to Contact Your Surgical Team

If you're already scheduled for surgery, start with the orthopedic office or the contact number in your preoperative instructions. Tell the person answering that you're scheduled for joint surgery and have noticed a skin change.

Make the call easy to act on

Have your name, date of birth, procedure, and surgery date available. Describe the area briefly, including where it is and when it appeared. If your operation is soon, say so at the start of the call.

Ask how and when the team will respond. Write down the name or role of the person you spoke with and the instructions you receive. If you're told to send a message or contact another clinician, make a note of that direction, too.

Send a photo if the team requests one

A photo may help your team see the area, but it doesn't replace a phone call or an examination. Use the secure method your office provides and include the date the photo was taken.

Good lighting and a clear view of the location can make the image more useful. You can also describe how the area feels and whether it has changed, since a picture can't show every symptom.

Protect Your Skin and Follow Your Surgery Instructions

While you wait for guidance, keep following the instructions your surgical team already gave you. Tell the team about any products you've applied and ask before adding something new to the affected area.

Avoid changing your preparation on your own

Don't scratch, pick at, or shave over irritated or broken skin. If your preoperative washing instructions involve the affected area, tell the team about the skin change and ask for direction.

Continue to follow the instructions you've received for bathing and other surgery preparations. Your care team can give you advice that fits the location and condition of your skin.

Keep your medication plan consistent

Don't stop or change a prescription on your own because you've noticed a rash. This includes steroids, medicines for rheumatoid arthritis, and other drugs that affect the immune system. Tell the surgical team and the prescribing clinician about the change.

If you take a medication for rheumatoid arthritis, have its name, dose, schedule, and most recent dose available. Our guidance on rheumatoid arthritis medications before surgery explains why the rheumatologist and surgical team coordinate that plan.

What Happens After You Report a Skin Change

Your team may ask follow-up questions or arrange to look at the area. They may also coordinate with your primary care clinician or another clinician involved in your care.

Your health history helps guide the review

Tell the team about conditions such as diabetes, immune-system disorders, or a history of skin infections. These details can affect how your clinicians assess your health before an operation.

Recent antibiotics and other changes in your health matter as well. Give your team the full picture, even if another clinician has already heard about the skin concern.

Keep your instructions close at hand

After speaking with the team, write down any directions about the next appointment, medication schedule, or surgery preparation. If you receive new instructions, keep them with your preoperative paperwork.

If the skin changes again before you've heard back, contact the office with the update. Continue to follow your existing instructions unless a member of your care team gives you different directions.

Speak Up Before Surgery Day

A rash before surgery deserves a call, even when you're unsure what caused it. Your surgeon can use the location, symptoms, and your health history to decide what information is needed next.

Report the change early and keep your care team informed if it looks or feels different. A short conversation before surgery can give everyone a clearer picture of your health.
