What can you do if you lower back pain in early pregnancy. Immerse yourself in water so long as it’s not very hot. Water allows your muscles to relax and get a break from all the demands your body is making on them right now. Talk to your doctor about strengthening and flexibility exercises for your lower back. If nothing else seems to work, talk to your doctor about icing or heating your back. In the coming months, be particularly careful while leaning, changing, picking up, and putting down. Lift with your legs, pull weights, like small children, in close to your body, and look up as you lift. Your baby may have caused you a bit of unavoidable back pain while in residence, but while in your arms, you should make sure that they give you as little pain and as much pleasure as possible.
