I'm 37 weeks pregnant and having pain in my lower left and right back. while sleeping at night, the pain seems to get worse on whatever side i lay on?

Back pain is not: Uncommon. Try some tylenol (acetaminophen) prior to sleep or even tylenol (acetaminophen) pm. On the other hand, you may have insomnia that is preventing deep wave sleep and adding to your muscle spasm. Do u clinch your teeth at night? This can sometimes contribute to pain. With poor sleep i always inquire about stress, worry, sadness, guilt, daytime tiredness, to determine whether your issue is related to stress, mood issue.
