Water Blisters on Swollen Legs: What Families Should Know

Water blisters that appear on the legs of elderly people need to be taken seriously: never assume that it’s simply a skin problem. Your loved one needs to be assessed by a healthcare professional so that the underlying cause can be identified and treated.

Oedema blisters on the legs can develop when significant fluid builds up in the tissues and the skin becomes stretched and fragile. They may also rupture, leaving fluid leaking from damaged areas of skin. The most important point to understand is that the visible blister may be a symptom of a more serious underlying issue

Oedema is the medical term for swelling caused by fluid collecting in the body's tissues, often in the feet, ankles and legs. The swelling could become severe enough to put pressure on and stretch the skin until blisters form.

If you notice oedema blisters on your elderly loved one’s legs, they need a medical assessment right away. Several serious underlying conditions can cause this degree of swelling:

• Damage or blockages in this system can cause fluid buildup (known as lymphoedema).
• When the heart isn't pumping blood effectively, fluid easily pools in the lower body.
• If the kidneys are struggling, they can't properly rid the body of excess fluid. Problems with the liver can also trigger severe swelling because it can disrupt the body's fluid balance.
• The veins may be struggling to send blood back up to the heart.

It is also worth noting that sitting or lying down for too long, as well as certain medications, can cause fluid buildup. Even so, you shouldn't try to guess the cause yourself. Please reach out to a doctor if you notice any major swelling or new blistering.

They will need to look at these symptoms alongside your loved one's current medications to decide on the best next steps.

Infection prevention is one of the important aspects of wound management. At Right At Home Central London, our goal is to reduce your risk of complications to support a smoother recovery at home. 

Our wound care specialists work closely with an experienced Infection Prevention and Control Specialist Nurse to ensure that you receive safe and high-quality care. These professionals also create the clinical standards and best practices your Carer follows throughout your care.

Our Registered Nurses also receive ongoing training in infection prevention and control, so they’re always up-to-date with current clinical guidance and evidence-based practice.

To ensure that you receive the best home care services, their training includes:

• Aseptic non-touch technique (ANTT).
  
• Safe wound assessment and dressing management.
  
• Infection prevention and control procedures.
  
• Recognising the early signs of possible complications.
  
• Knowing when to escalate concerns to your GP or other healthcare professionals.
  

Important: Call 999 immediately if your loved one develops chest pain or severe breathing difficulties alongside leg swelling. This is a medical emergency.

Seek urgent medical help if: 

• Your loved one has a fever or is generally feeling very unwell.
• Only one leg suddenly becomes swollen or unusually warm to the touch. This can be a sign of deep vein thrombosis.
• You notice spreading redness, heat, increased pain, or swelling (which could point to cellulitis, a deep skin infection). 

If there are no emergency symptoms but the swelling is new or seems to be worsening, contact their GP or call NHS 111.

The doctor’s main focus will be finding and treating the root cause of the fluid buildup. Depending on what they find, treatment might involve:

• Adjusting their current medications
• Prescribing water tablets (diuretics) to help clear the extra fluid
• Using compression therapy (this should only be started after a healthcare professional has confirmed it is safe for them)

While you are waiting to see a doctor or helping your loved one follow their current care plan, you can take these steps to keep their skin safe from further damage:

1. Never pop or pick at the blisters on legs from swelling. Keeping them intact forms a natural barrier that protects the delicate skin underneath from bacteria. If a blister has already burst or the skin is weeping fluid, reach out to a healthcare professional for advice on the right way to clean and dress the area.

2. Try to eliminate friction around the legs. Avoid tight socks or shoes that dig into the skin, as these will only cause more discomfort. 

3. Ask their doctor before you elevate their legs or change their diet. Don’t introduce compression without the doctor’s permission. Always wait for a professional medical assessment first.

The most important thing you can do is monitor their legs closely. Reach back out to their medical team right away if you notice the swelling increasing and/or the skin breaking.
