Why Ribs and Skin Feel Sore During the Third Trimester

In the last few months of your pregnancy, you might develop some rib and skin soreness. It’s quite natural because your body is growing to accommodate the development of your foetus. During this time, your uterus pushes upward and your skin stretches, which can make your body feel a bit tender. Understanding why this happens helps you manage the soreness better, stay comfortable, and know when it might be time to consult your physician.

When you enter your third trimester, your body begins its final stage of getting ready for childbirth. During this time, many women experience new discomfort, such as rib pain, and their skin becomes sore. You might feel dull, sharp, or pressing pain around your ribs, along with itching or tightness across your skin. While these symptoms may worry you, they're usually a natural part of the third trimester.
Let's check out why this is happening, what you expect, and how to feel better.

Why Does Rib Pain Occur During the Last Trimester?

Your baby already grows pretty big in the third trimester, almost 2-3 kgs, and over 15 to 18 inches. With the growth of your baby, your uterus stretches way up, pushing on your ribs. Some other reasons include:

Your Womb is Expanding

Soreness can be caused by your growing womb as it puts more strain on the nerves, muscles, and bones around your ribs. You’ll probably have to deal with it more if you sit for a while or bend down.

Baby's Kicks

If the baby's feet are close to your ribs, you might have to deal with some stretching or sharp kicks. Some babies stay in this spot for weeks, which can make you constantly sore.

Hormonal Tenderness of Joints

Hormones like relaxin loosen your ligaments to get your pelvis ready for birth. However, this also affects the joints around your ribs, making them more prone to discomfort or increased sensitivity.

Why Does Your Skin’s Sensitivity and Tenderness Increase?

During the later months of pregnancy, your skin will become tender. It is probably due to the fact that your skin is stretching to accommodate your growing foetus, your body is retaining more water, and your blood flow is shifting. Basically, your skin is putting in extra work to support your growing baby, and that can make it uncomfortable.

Skin Stretching Faster

Your belly can grow up to 1 centimetre each week in the final months. When the skin stretches, the little nerves beneath it get irritated, which leads to itching or soreness.

More Blood Flow

When you’re pregnant, your blood volume goes up by 40 to 50%. This additional circulation can make your skin feel tight, warm, or tender.

Pregnancy-related Itching

Hormonal changes and stretched skin can increase sensitivity in the breasts, abdomen, and sides. Some individuals also experience dryness, which exacerbates symptoms and increases discomfort.

Oedema or Fluid Retention

When fluid accumulates under the skin, it can make tissues feel swollen and tender.

Does Tenderness Indicate Something Alarming?

Soreness in the ribs and skin is quite natural in most of the cases. However, it's important to remain vigilant for symptoms that may indicate an underlying issue.
You should contact your doctor if you notice:
  • Severe pain on the right side under your ribs
  • Sudden or severe pain that doesn't go away
  • You might have a hard time breathing
  • Swelling accompanied by high blood pressure

How to Reduce Rib Soreness During the Last Trimester?

Here are some easy things you can do to feel better:
  • Don’t sit for too long. Keep yourself active.
  • Try to make your back and ribs comfortable with a pregnancy pillow
  • Do some prenatal stretches to loosen up your ribs
  • Put a warm compress on any sore muscles; the heat can help them relax
  • Sit upright with support, as good posture reduces strain on your ribs
  • Wear clothing that allows your skin to breathe. Tight things can make you feel worse.

What Can Help When Your Skin Feels Sore and Stretched?

Skin problems can make your days even harder during pregnancy, but you can always find ways to ease them:
  • Keep your skin moisturised with gentle lotions with zero fragrance
  • Skip the extremely hot showers that can lead to dryness
  • Use gentle soaps to avoid dry skin
  • Choose cotton clothes over anything to avoid skin irritation
  • Apply a cold compress as they help soothe warm or itchy areas

How Can Your Partner or Family Offer You Emotional Support?

Being physically uncomfortable can really mess with your feelings when you’re in your last trimester. You might feel irritable, extremely tired, or just extra sensitive. Talking to your partner or family about how you’re feeling can help them get what you need.
Emotional support could be things like:
  • Giving you soft massages
  • Helping you get comfy to stay relaxed
  • Listening when you feel emotionally worn down
  • Telling you to take it easy and rest
  • Helping with daily chores to reduce pressure

What’s Next?

  • Change your sleeping or sitting postures daily
  • Note when the rib and skin soreness gets intensified
  • Try not to sit or stand for too long
  • Use lotions to prevent itching or dry skin
  • Try to stay active all day long
  • If something feels really wrong, call your doctor

In the third trimester, rib pain and skin sensitivity can happen because of hormonal changes, your growing baby, and your body's stretching. While these symptoms can overwhelm you, you can manage them with simple lifestyle modifications. Listening to your body, seeking help, and consulting your physician when necessary helps you remain comfortable and emotionally balanced as you approach the birth of your baby.
