Third Trimester: Pain Causes and Remedies You Need to Know

The third trimester of pregnancy is an exciting time, but it can also bring a range of discomforts as the body prepares for labor. Whether it's the pressure in your lower abdomen or persistent aches all over, knowing what pains are normal and how to ease them can help you manage these last few months. Here's a guide to understanding what pains are normal in the 3rd trimester, tips on how to ease stomach pain in the third trimester, and advice on other common discomforts.

Common Pains in the Third Trimester

As you enter the final months of pregnancy, your body undergoes significant changes that can cause a variety of aches and pains. These symptoms can include whole body pain during the third trimester to more localized issues like lower stomach pain or sharp pelvic pain during the third trimester. Many of these discomforts are completely normal, but they can still be bothersome.

Lower Back and Pelvic Pain in the Third Trimester

As your baby grows, your center of gravity shifts, putting additional strain on your back, hips, and pelvis. Lower back pain and sharp pelvic pain during pregnancy third trimester are common as your body adjusts. These pains often stem from hormonal changes that loosen your joints and ligaments to prepare for childbirth. Additionally, the extra weight can put pressure on your lower back and pelvis, especially when standing or walking for long periods.

What you can do: Doctors at Northwestern University Medicine recommend using a heating pad on your back, wearing maternity support belts, or trying stretching to relieve tension. If the pain is severe or shooting down your legs, consult your doctor about physical therapy or visit a chiropractor who specializes in pregnancy care.

Stomach and Abdominal Pain in the Third Trimester

Lower abdominal pain, including pressure in the abdomen during the third trimester, can occur as your uterus expands and presses against surrounding organs. One-sided pain in the third trimester is also common, as the growing uterus can stretch ligaments, causing discomfort. It can also be caused by normal factors like the growing uterus putting pressure on organs, gas, constipation, or Braxton Hicks contractions (false labor pains). That being said, if the pain is severe, constant, accompanied by other symptoms like bleeding, or feels significantly different than usual, it's important to contact your doctor as it could indicate a more serious issue like preeclampsia or placental abruption.

What you can do: To ease abdominal pain in the third trimester, take breaks to rest and elevate your feet when possible (UT Southwestern Medical Center). You can also try wearing a maternity support band to alleviate some of the pressure from the growing belly (Northwestern Medicine). If you experience sharp pelvic pain during pregnancy third trimester (also known as "lightening crotch"), this could also be due to the pressure your baby's head exerts on your cervix, which is normal but should be monitored.

Pain Relief and Remedies for the Third Trimester

During the third trimester, you may experience various types of pain, ranging from mild aches to more intense discomfort. It's important to know what pain relief can you take in the third trimester of pregnancy and how to manage it effectively without harming your baby.

Medication Options

Some pain relief options, like Tylenol, are considered safe during pregnancy, but it's important to avoid stronger painkillers unless advised by your doctor. Over-the-counter antacids can help with heartburn, which often worsens as the pregnancy progresses. However, any medication should be taken in moderation, and you should always consult your physician before using them.

Natural Remedies

Non-medical remedies can also help ease discomfort. For whole body pain during the third trimester, regular exercises like walking, yoga, or light weightlifting can help keep your muscles and joints flexible, reducing pain. Additionally, practices like using lavender scents or taking a warm bath before bed can help with relaxation and improve sleep quality.

Compression and Elevation

For swelling and discomfort in the legs and feet, compression stockings can help reduce fluid retention, while elevating your legs at night can improve circulation. This simple measure can also relieve some of the pressure that contributes to lower back and hip pain.

Dealing With Stomach and Digestive Discomfort

Many women experience heartburn or digestive discomfort during the third trimester as the growing uterus compresses the stomach and digestive organs. This can lead to lower stomach pain or bloating. To manage heartburn, avoid eating large meals before bedtime, and opt for smaller, more frequent meals. Steer clear of acidic or fatty foods, as these can worsen reflux. Sleeping with your head elevated and staying upright after meals can also help.

Dealing With Pressure and Pain in the Lower Abdomen

If you're experiencing pressure in the lower abdomen during the third trimester, this can be caused by the baby's position or the increasing pressure on your pelvis as your baby grows. A maternity support band can help distribute the weight more evenly, easing some of the strain on your abdomen (Northwestern Medicine). However, if the pain is sudden, severe, or if you notice any abnormal bleeding, it's important to contact your healthcare provider right away.

When to Be Concerned: Danger Signs of Pregnancy in the Third Trimester

Although many aches and pains are a normal part of pregnancy, some symptoms should not be ignored. Pay attention to the following danger signs of pregnancy in the third trimester:

  • Sudden, severe abdominal pain or cramping that doesn't subside
  • Bleeding or heavy spotting (consult your doctor immediately)
  • Sudden swelling or swelling that is asymmetrical (this could signal a blood clot or preeclampsia)
  • Severe headaches, vision changes, or sudden weight gain, which could indicate preeclampsia
  • Sharp pain in the left or right side of your body, particularly if it's accompanied by nausea, fever, or other concerning symptoms (this could signal a complication like a kidney infection)

If any of these symptoms occur, contact your doctor immediately to ensure both you and your baby are safe.

As you approach the finish line of your pregnancy journey, it's important to take care of yourself and manage the various aches and discomforts that come with the third trimester.
