Pregnancy Back Pain Relief
Home Remedies for Relieving Back Pain in Pregnancy
- Applying a hot water bag or a heating pad (make sure the temperature is not too high; wrapping the hot water bag with a towel helps to avoid excessive temperature) 
- Applying a cold compress to the painful area to relax the sore muscles  (make sure the ice pack is not too cold; avoid applying it for an extended period of time)
- Taking a warm bath 
- Bed rest
- Asking a friend to rub the painful area gently
Light exercises like pelvic tilts , walking and stretching can help. But, avoid forcing yourself to exercise too hard as it may strain the ligaments further or harm the baby. Here is a simple exercise technique to help ease the pain :
- Begin by resting in a box position, with your knees under the hips, your hands under the shoulder and your fingers facing forward
- Make sure your abdomen is lifted high enough to keep the back straight
- Next, pull in the stomach muscles before lifting your back up in the direction of the ceiling while curling the trunk and letting your head relax gently forward (do not lock the elbows)
- Hold in this position for a few seconds before slowly returning to the previous (box) position (keep your back straight)
- Repeat the whole procedure slowly 10 times
This exercise helps to strengthen your muscles; but be careful not to put too much pressure on your back or you may hurt it further.
Water exercises and swimming are good for your back as well (make sure to avoid the styles that are likely to strain your neck and back) .
