Panicking over my big leg!
QMy left leg has become swollen and puffy, and my doctor’s sent me for urgent tests. Is it serious? Mary, Carlisle
A Swollen legs and puffy ankles are common, especially in warm weather, and often don’t mean anything.
But some causes can be serious, particularly when just one leg’s swollen.
One possibility is a DVT, a clot in the deep veins inside your leg. Another is blockage of the lymph vessels (which drain excess fluid from your leg), sometimes due to cancer invading lymph glands.
Pregnancy, a cancerous tumour or a lump in your pelvis, such as a large cyst on your ovary, might also cause your leg to swell.
Tests might include urine and blood tests, an ultrasound scan of your pelvis and groin, X-rays and a Doppler scan to check blood flow in your legs.
