Varicose Veins & Leg Cramps in Pregnancy
Aching, heavy legs, visible varicose veins and night-time calf cramps are common in the second half of pregnancy. At Modern Physio we focus on understanding the root-cause of your problem & personalizing your treatment for lasting results.
Understanding Varicose Veins & Leg Cramps in Pregnancy
Aching, heavy legs, visible varicose veins and night-time calf cramps are common in the second half of pregnancy. The circulatory demand of pregnancy, the pressure of the growing uterus on the veins returning blood from the legs, and hormonal effects on vein walls all contribute. Most of this is uncomfortable rather than dangerous — but leg symptoms in pregnancy are also one of the situations where a serious cause must be excluded first, because a blood clot can present as calf pain and swelling. This page covers both what helps and what should never be self-managed.
Common Symptoms
- Aching, heaviness or throbbing in the legs, worse by the end of the day
- Visible, bulging veins in the legs
- Night-time calf cramps
- Mild swelling of the ankles and feet
- Itching over the affected veins
- Symptoms that ease when the legs are elevated
How Common Is It?
Varicose veins and leg cramps are frequently reported in the later stages of pregnancy. Varicose veins often improve in the months after delivery, though they may not resolve completely.
Causes & Risk Factors
- Increased blood volume during pregnancy
- Pressure from the growing uterus on the veins returning blood from the legs
- Hormonal relaxation of vein walls
- Prolonged standing or sitting
- A family history of varicose veins
- Reduced calf muscle pumping activity
Our Diagnosis Process
- History of the symptoms, when they occur, and what relieves them
- Checking for the urgent features below — one-sided calf pain, swelling, warmth or redness needs same-day medical assessment for possible blood clot, before anything else
- Assessment of calf muscle function, ankle movement and walking pattern
- Review of standing and sitting load through the day
Our Treatment Approach
- Calf pump exercises and ankle movement to assist venous return, taught to be done frequently
- Advice on elevation, positioning and movement breaks
- Graduated compression stockings where advised medically — sizing and fit matter
- Walking and general activity, which supports circulation
- Calf stretching and hydration advice for night cramps
- Immediate referral where the presentation could be a blood clot
Recovery & Prevention Tips
- Move your ankles regularly whenever you are sitting or standing still
- Elevate your legs when resting, ideally above hip level
- Sleep on your left side, which reduces pressure on the main vein returning blood from the legs
- Walk daily — the calf muscles are the pump that moves blood back up
- Stretch your calves before bed if you get night cramps

NHS — Varicose veinsFrequently Asked Questions
When is leg pain in pregnancy an emergency?
Pain, swelling, warmth or redness in ONE calf needs same-day medical assessment, because a blood clot must be excluded. Do not massage a painful, swollen calf and do not wait to see if it settles. This is the single most important point on this page.
Will varicose veins go away after delivery?
They often improve substantially in the months after birth, though they may not disappear entirely. Persistent varicose veins are a matter for medical assessment rather than physiotherapy.
Do compression stockings help?
Many women find them helpful for aching and heaviness. Correct sizing and grade matter, and they should be recommended medically rather than bought at random.
What causes night cramps and what stops them?
The cause is not fully established. Calf stretching before bed, staying hydrated and regular walking help many women. If cramps are severe or associated with weakness, raise it with your doctor.
Is massage safe for my legs in pregnancy?
Not if a clot has not been excluded — this is why one-sided calf symptoms get assessed medically first. Physiotherapy here runs alongside your obstetrician or gynaecologist, never instead of them. Dr. Surabhi Bansal is a physiotherapist, not a physician: the clinic does not prescribe medication and has no imaging or scanning on site.
