Unfortunately, hip pain is common in pregnancy, as your body's joints loosen up ready for labour. You may notice your hips are more painful at night in bed. You're probably finding it hard to get a good night's sleep.
Sleep on your side with legs bent and a pillow between your knees supporting the whole length of your leg. This position will support all the joints around your pelvis and hips. If this doesn't help, experiment with pillows and cushions until you find something that suits you.
Put an extra layer of padding, such as a sleeping bag or quilt, under your bottom sheet.
Resting when you can during the day will ease your pain at night. You will probably find that your pain is worse if you have had a busy day. Your body releases hormones which relax your ligaments, the tough, flexible tissues that connect your bones and support your joints. To lessen the strain on your joints, try to spend time resting on a birth ball or on your hands or knees. This takes the weight off your hips.
If you need help with walking, ask to see a physiotherapist. Your physiotherapist can supply elbow-crutches, to take the pressure off your hips, and tummy support belts. She can give you hands-on therapy and suggest exercises to practise at home.
