Pregnancy journey
Some women will develop pain in their pelvis at later stages of pregnancy. This may happen during walking or when getting in and out of bed or a car. This is known as pelvic girdle pain (PGP) or symphysis pubis dysfunction (SPD).
PGP is caused by the hormone relaxin which your body produces in pregnancy to allow it to stretch and grow your baby. Although PGP can be very painful to you, it will not harm your baby.
The pain may be worse on movement – walking, going up and down the stairs, movement using one leg, turning over in bed, moving legs apart – e.g. getting out of the car.
If you are experiencing symptoms of PGP and are concerned please contact your maternity team. Your midwife or GP may refer you to physiotherapy which may help.
You may be advised to:
You will still be able to have a vaginal birth with PGP and it isn’t usually recommended you have an induction of labour for this reason alone. Using a birthing pool may assist with the pain of PGP and labour, taking pressure off your joints. Other pain relief is available for you including an epidural.
PGP pain usually improves following the birth of your baby, with only 1 out of 10 women still experiencing ongoing pain. It is advised if this happens, to continue the above advice, with regular pain relief and heat therapy. Physiotherapy may also continue to help if required.
For more information on PGP in pregnancy please access the NHS website here , the Royal College of Obstetricians and Gynaecologists patient information leaflet here , and the society of Pelvic Obstetric and Gynaecological Physiotherapy (POGP) leaflet here .
‘Your body’s journey during pregnancy and after birth’ videos on the link here have been developed by the pelvic health physio team at Imperial College Hospital, London. They are a fantastic resource that we urge you to view them.
The videos include 'pelvic floor exercises during and after pregnancy' and 'back and pelvic pain during pregnancy'.
