How to Relieve Diverticulitis Pain Quickly

Medically reviewed by Moshe Barnajian, MD, FASCRS, colorectal surgeon at Surgery Group LA · Reviewed October 14, 2026

For a mild diverticulitis flare that a doctor has already checked, the quickest relief usually comes from three things: resting your bowel with clear liquids for a few days, a heating pad on your belly, and acetaminophen (Tylenol) for pain. Avoid ibuprofen (Advil, Motrin) and naproxen (Aleve), which can make complications more likely. If this is your first flare, or you have a fever, severe pain or vomiting, see a doctor first. Diverticulitis sometimes needs antibiotics or hospital care.

What a diverticulitis flare feels like

Diverticulitis happens when one or more small pouches in the wall of the colon (diverticula) become inflamed. The pain is usually in the lower left side of the belly and often comes on suddenly, though it can start mild and build over a few days. Fever, chills, nausea, vomiting, and constipation or diarrhea are common too (NIDDK).

Other problems, such as appendicitis, a kidney stone or an ovarian cyst, can feel similar. That's why a first episode should be checked, usually with an exam and often a CT scan, before you treat it at home (Cleveland Clinic).

How to relieve diverticulitis pain quickly at home

If your doctor has said your flare is mild and can be treated at home, these steps help most:

1. Rest your bowel with clear liquids. For a few days, stick to broth, water, pulp-free juice, gelatin, ice pops, and tea or coffee without cream. If you feel better in 2 to 3 days, start adding low-fiber foods (Mayo Clinic).
2. Use a heating pad. Warmth on the belly can ease cramping and pain (UMass Memorial Health).
3. Take acetaminophen, not NSAIDs. More on this below.
4. Take antibiotics only if prescribed, and finish them. Not everyone with mild diverticulitis needs antibiotics (NIDDK). If you're given them, take every dose even after you feel better (Mayo Clinic).
5. Rest. Take it easy for a few days and let the inflammation settle.

Most mild flares start to ease within a few days. If you're not improving after 2 to 3 days on clear liquids, call your doctor.

Does a heating pad help diverticulitis pain?

Yes, for many people. A heating pad or hot water bottle on the lower belly can ease the cramping pain of a flare (UMass Memorial Health). Use a low or medium setting, put a cloth between the pad and your skin, and don't fall asleep with it on. Heat eases discomfort; it doesn't treat the inflammation. If pain keeps getting worse despite heat, that's a reason to call.

Can I take Tylenol for diverticulitis pain?

Yes. Acetaminophen (Tylenol) is the over-the-counter pain reliever doctors usually recommend for diverticulitis (Cleveland Clinic). Follow the dose on the label, and don't take more than the label allows each day.

Your doctor may also prescribe an antispasmodic, a medicine that relaxes the bowel and eases cramping (NIDDK).

Tylenol or ibuprofen for diverticulitis?

Choose Tylenol. Ibuprofen (Advil, Motrin), naproxen (Aleve) and aspirin are NSAIDs (nonsteroidal anti-inflammatory drugs). NSAIDs can raise the risk of diverticulitis complications and bleeding in the gut (NIDDK; Cleveland Clinic). So, can you take Aleve with diverticulitis? It's best not to unless your doctor tells you to. If you take aspirin for your heart, don't stop it on your own; ask your doctor.

Is tea good for a diverticulitis flare-up?

Plain tea without cream or milk counts as a clear liquid, so you can drink it during a flare (Mayo Clinic). Many people find a warm cup soothing. Chamomile, peppermint or ginger tea are fine if they sit well with you, but no tea has been shown to treat diverticulitis or shorten a flare. Check with your doctor before trying herbal supplements, especially if you take other medicines.

What to eat as the flare settles

As you feel better, add low-fiber foods in small meals: eggs, fish, chicken, tofu, white rice, pasta, white bread, bananas, applesauce, and cooked vegetables without skins or seeds (Mayo Clinic). Keep drinking water.

Once you've fully recovered, slowly go back to a high-fiber diet. Fiber helps lower the chance of another flare. You don't need to avoid nuts, seeds or popcorn; there's no evidence they cause flares (Mayo Clinic). For more, see how to prevent a diverticulitis flare-up.

Do probiotics help?

A few small studies suggest probiotics might help prevent new flares, but there isn't enough evidence to recommend them (Mayo Clinic). If you'd like to try one, ask your doctor first.

When to call your doctor

• You think you're having a flare and haven't been seen yet.
• You're not getting better after 2 to 3 days of clear liquids.
• You have a fever of 100.4°F or higher, or chills.
• You have nausea or vomiting.

Get care right away if

• you have severe or worsening belly pain, or your belly feels hard and very tender (Cleveland Clinic);
• you can't keep clear liquids down (Mayo Clinic);
• you have bleeding from your rectum (UMass Memorial Health);
• you feel faint, weak or look pale.

These can be signs of an abscess, a tear in the colon or bleeding, which need urgent treatment.

How we treat diverticulitis at Surgery Group LA

We start by confirming it's diverticulitis, usually with an exam and a CT scan, and checking for complications. Many flares settle with a liquid diet, pain control and, when needed, antibiotics. Once you've recovered, a colonoscopy is often recommended about 6 weeks later to check the colon (Mayo Clinic). Surgery to remove the affected part of the colon is considered after complications, or when flares keep coming back.
