What Causes Swollen Feet or Persistent Itching & What Should I Do?

Let’s be honest, foot problems don’t usually get much attention until they start affecting your day. One minute you’re fine, the next you’re Googling “Why are my feet so itchy at night?” or “Why do my ankles look like balloons after work?”

If that’s you right now – don’t stress. Swollen feet and persistent itching are two of the most common complaints we hear at Thames Foot Clinic, and while they can be linked to something serious, more often than not, they’re your body’s way of saying something is ‘off’.

Here’s what might be going on, and what you can actually do about it.

Swollen Feet: What’s Causing the Puffiness?

Swelling (or oedema, if you want to be technical) is often fluid build-up. It’s common, especially if you’re on your feet all day or sat still for too long. But there are a few reasons it can happen:

Standing or sitting for hours – Gravity pulls fluid down, and your feet cop the lot.
Hot weather – Heat causes your veins to expand, which can slow down circulation.
Poor circulation or vein issues – Like varicose veins or more complex vascular problems.
Pregnancy – The body holds onto more fluid, especially in the third trimester.
Injury – Sprains or broken bones = inflammation = swelling.
Underlying health conditions – Heart, kidney, or liver issues can all show up through swollen feet.

What to do:

Start simple. Elevate your feet when you’re resting. Try compression socks. Stay hydrated. And if the swelling is one-sided, sudden, or painful, get it checked. That’s not one to wait on.

Itchy Feet: What’s Causing the Scratch?

That annoying, can’t-stop-scratching itch? Could be a bunch of things. The trick is spotting the patterns.

Athlete’s foot (fungal infection) – Red, flaky skin. Often between the toes. Loves warm, damp socks.
Dry skin or eczema – Especially in winter, or if you’re using harsh soaps.
Allergic reactions – New laundry detergent? Walking barefoot somewhere new?
Nerve issues – Burning, tingling, or random itchiness could be linked to diabetes or circulation problems.

What to do:

First, keep your feet clean and dry. Change socks regularly (especially if you’ve been sweating). Moisturise daily and avoid perfumed lotions if your skin’s sensitive. If it looks fungal, use an antifungal cream for a few days and if nothing changes, time to book in.

When Should You See a Podiatrist?

If the swelling or itching:

Comes back daily
Worsens overnight or with activity
Is paired with pain, numbness, or skin changes
Doesn’t clear up with basic self-care

Final Thoughts

Swollen feet and itchy skin might seem minor, but they can be early signs of something your body’s trying to flag. And even if it is something simple, living with it day in, day out isn’t exactly ideal either.

So whether it’s moisture, movement, shoes, or something medical – don’t ignore it. Your feet do a lot for you. Might be time to return the favour.
