When arthritis flares up, the priority is reducing pain and inflammation as quickly as possible while protecting the joint from further irritation. A flare can last anywhere from a few days to several weeks, and what you do in the first 24 to 48 hours makes a real difference in how long it lingers. The steps below work for both osteoarthritis and rheumatoid arthritis flares, with some important distinctions between the two.
Ice, Heat, or Both
Choosing between ice and heat depends on what’s happening in the joint. If the joint is visibly swollen, warm to the touch, or red, start with ice. Cold reduces inflammation and dulls pain signals. Wrap an ice pack in a thin towel and apply it for 20 minutes at a time, with breaks in between. Applying heat to an actively inflamed joint can increase blood flow to the area and make swelling worse.
Heat works better for stiffness without much swelling. A warm bath, heating pad, or warm paraffin wax loosens tight muscles and increases flexibility. Limit heating pads to 20 minutes per session to avoid burns. A practical approach many people find helpful: use heat before any gentle movement to loosen the joint, then ice afterward to calm any resulting ache.
Over-the-Counter Pain Relief
For a flare that’s more than mildly uncomfortable, an anti-inflammatory pain reliever like ibuprofen can reduce both pain and swelling. The typical over-the-counter dose is 200 to 400 mg every four to six hours as needed, with a daily maximum of 1,200 mg. Don’t use it for more than 10 consecutive days without talking to your doctor. Naproxen is another option that lasts longer per dose, so you take it less frequently.
If you can’t take anti-inflammatories because of stomach issues, kidney concerns, or blood thinner use, acetaminophen helps with pain but won’t reduce inflammation. Topical options are worth considering too. Creams containing capsaicin, the compound that makes chile peppers hot, temporarily block pain signals from the nerves when rubbed into the skin over the affected joint. They take a few days of consistent use to reach full effect, and you should wash your hands thoroughly after applying.
Protect the Joint Without Stopping All Movement
The instinct during a flare is to stop moving entirely, but complete immobility can actually increase stiffness and make recovery slower. The goal is relative rest: scale back intensity and duration, but keep the joint gently moving through its range of motion. If you normally walk for 30 minutes, try 10. If you lift weights, switch to bodyweight movements or skip resistance entirely for a few days. Longer breaks between activity sessions help too.
If mornings are the hardest part of your day, start with the gentlest movements you can manage. Slow, controlled bending and straightening of the affected joint, done without load or resistance, keeps fluid moving through the joint capsule and prevents the stiffness from compounding. If a flare persists and you can’t find a comfortable level of activity, a physical therapist can help build a modified routine that keeps you moving without aggravating the inflammation.
How Flares Differ by Arthritis Type
Osteoarthritis flares and rheumatoid arthritis flares feel different because they have different causes, and recognizing which you’re dealing with shapes how you respond.
Osteoarthritis pain comes from cartilage wearing down until bone contacts bone. Flares tend to build gradually, often triggered by overuse or a change in activity. Morning stiffness is common but usually resolves within a few minutes of moving around. The joints most often affected are knees, hips, the lower back, and the joint closest to the fingertip.
Rheumatoid arthritis is an immune system problem. The body attacks its own joint tissue, causing inflammation that can surge unpredictably. RA flares often affect the hands, wrists, and feet, and morning stiffness lasts an hour or longer. Some people feel generally unwell during a flare, with fatigue, low-grade fever, and weakness that resembles the early stages of a flu. If you have RA and your flare is severe or lasts more than a few days, it may signal that your current treatment plan needs adjusting. Contact your rheumatologist rather than trying to ride it out on over-the-counter medication alone.
Sleeping Through a Flare
Pain that worsens at night is one of the most frustrating parts of a flare. Strategic pillow placement can take pressure off inflamed joints and make a meaningful difference.
- Knees and hips: Back sleepers should place a pillow under the knees. Side sleepers should lie on the side that isn’t painful and put one or two pillows between the knees to keep the hips aligned.
- Shoulders: Side sleepers should avoid lying on the painful side. Place a thick pillow under the arm of the sore shoulder to keep it elevated. Back sleepers can place a pillow under each arm, or use a wedge to prop the upper body at about a 45-degree angle.
- Hands and wrists: A lightweight splint holds the wrist in a neutral position overnight, reducing the aching that comes from unconsciously bending the joint while you sleep.
- Neck: The goal is a neutral spine. Back sleepers do best with a thin pillow. Side sleepers need a taller one so the head and neck stay in a straight line. Avoid sleeping on your stomach if your neck is involved.
- Feet: When even the weight of a blanket causes pain, blanket lifters attach to the mattress and hold sheets above your feet and lower legs.
When a Flare Needs More Than Home Care
Most flares respond to the combination of rest adjustments, thermal therapy, and over-the-counter medication within a week or two. But some don’t settle down. If pain remains severe after consistent home management, a corticosteroid injection directly into the joint is the typical next step. These injections are generally reserved for flares that haven’t responded to oral pain relievers or anti-inflammatories. For joints like the hip, guidelines specifically note that injections should be considered when a flare is unresponsive to standard medication. Repeat injections need spacing of at least two to three weeks apart, and the series is stopped once relief plateaus.
Red Flags That Aren’t a Normal Flare
A joint infection, called septic arthritis, can mimic a flare but requires emergency treatment. The key differences: septic arthritis causes intense pain that comes on fast, often within hours rather than days. The joint becomes extremely swollen, warm, and sometimes changes color. Fever is common. Using or bearing weight on the joint feels nearly impossible. If you have a joint replacement and develop new pain and swelling months or years after surgery, that also warrants urgent evaluation, as the implant may have loosened or become infected. Rapid onset of severe joint pain paired with fever is not something to manage at home.
