At the end of the day, most of us are tired, ready to kick up our feet and relax on the couch. But for many people, it’s not just tiredness from the day. Heavy legs that ache, are sore or cramp can often be a sign of something more than just daily fatigue. At the end of the day, if it feels like you’re dragging around bags of flour instead of legs, there is a chance it’s being caused by an underlying medical condition.

Heavy legs are often an indicator of one of the following conditions:

Varicose Veins

One of the most common causes of heaviness in the legs is varicose veins.

Varicose veins are caused by a wide range of factors, for a general overview, see Common reasons varicose veins form. 

Veins are responsible for carrying oxygen-rich blood from around the body, back up to the heart. However, when vein valves, or vein walls, become damaged they can lead to Chronic Venous Insufficiency (CVI). So, why do the legs feel heavy? When CVI occurs, blood is not able to flow back up to the heart and it begins to reflux or pool, forming twisted, enlarged vessels which often ache, especially after extended periods of walking or standing.

PAD (Peripheral Arterial Disease)

This occurs when fatty deposits build up on the walls of your arteries, restricting the blood flow. This most commonly occurs in the legs and is exacerbated by other factors such as smoking, high blood pressure, diabetes and high cholesterol. It often causes aches and cramping.


This is not a disease or medical condition so much as the result of too much force on the legs. More common in athletes, but also anyone who is running a lot, training for a marathon or straining the muscles in your legs too much, overtraining means the muscles don’t have time to repair themselves and leads to fatigue and heaviness. Most common in cyclists and runners.

Restless Leg Syndrome

Restless leg syndrome causes an uncomfortable feeling in the legs of heaviness, numbness and a throbbing shaky feeling whenever the legs are still. Movement relieves the symptoms, but unfortunately, there’s no clear cause.

What to do if my legs feel heavy at the end of the day

Whichever symptoms come along with the feeling of heaviness, it’s best to speak to your GP to get checked and diagnosed. From there you can confirm the best course of treatment. However, there are several things you can do yourself that help to manage heavy legs regardless of the cause.

  • Compression stockings: The use of medical-grade compression stockings is one of the most effective ways of treating heavy legs, as it boosts circulation to provide healthy blood-flow, stabilises the muscles for recovery and daily fatigue, and alleviates pain and twitching in the muscles.
  • Stretching and exercise: Keeping the legs moving is important for your vein health and general health. If you’re spending long periods of time sitting down for work, either at the desk or in the car, get up and move around a little every 20-30 minutes to keep the blood flowing and muscles moving.
  • Lifestyle: Changing your lifestyle to lose any excess weight, reduce cholesterol, fat and sugar in your diet, and quitting smoking are all great changes to make for your legs, and for your health as a whole.
