Most muscle aches resolve within a few days using a combination of temperature therapy, gentle movement, and basic over-the-counter options. The approach that works best depends on whether your soreness is from exercise, an injury, or something else entirely. Here’s what actually helps, what doesn’t, and how to speed up recovery.
Why Your Muscles Ache in the First Place
Your muscles are made of thousands of tiny fibers that stretch and contract as you move. During intense or unfamiliar exercise, some of those fibers develop microscopic tears. This is completely normal and actually how muscles grow stronger, but the repair process triggers inflammation that makes you sore.
Soreness that shows up 12 to 72 hours after a workout is called delayed onset muscle soreness, or DOMS. It’s especially common after “eccentric” movements, where a muscle is working while it lengthens. Think: lowering a heavy box to the ground, walking downhill, or the lowering phase of a bicep curl. DOMS typically peaks around 48 hours and clears up within three to five days. If soreness lasts a week or more, you may be dealing with a muscle strain rather than normal post-exercise aches.
Heat and Cold: Which One and When
Cold therapy works best for fresh injuries or acute inflammation. It numbs the area, reduces swelling, and limits bleeding into damaged tissue. Wrap an ice pack in a damp towel (never apply ice directly to skin) and hold it on the sore area for 15 to 20 minutes at a time.
Heat is the better choice for general muscle soreness and stiffness, particularly after exercise. It increases blood flow to the area, which helps clear out metabolic waste products and delivers the nutrients muscles need to repair. A warm bath, heating pad, or hot water bottle all work. Just avoid heat for the first 48 hours after an actual injury, since extra blood flow can worsen swelling in freshly damaged tissue. And keep a layer of fabric between any heating device and your skin to prevent burns.
A practical rule: if something is visibly swollen or just happened, reach for cold. If you’re stiff and achy from yesterday’s workout, use heat.
Foam Rolling for Soreness
Foam rolling is one of the more effective self-treatment options for DOMS. Research from James Madison University found that just three minutes of foam rolling on a sore muscle group significantly reduced perceived soreness at 48 and 72 hours compared to doing nothing. Interestingly, rolling for nine minutes didn’t produce better results than three minutes, so you don’t need to spend long on it.
Target each sore area for about one minute, rolling slowly back and forth. When you hit a particularly tender spot, pause on it for a few seconds before continuing. You can foam roll daily when you’re sore without worrying about losing muscle function.
Over-the-Counter Pain Relief
Anti-inflammatory medications like ibuprofen and naproxen are generally more effective for muscle aches than acetaminophen because they reduce inflammation in addition to blocking pain signals. Acetaminophen works fine for mild soreness but won’t address the underlying inflammatory process.
One option worth knowing about: you can take acetaminophen and an anti-inflammatory together. This combination can provide equivalent pain relief at lower doses of each, which reduces the side-effect risk of both. You can also alternate between the two throughout the day.
There’s a nuance here, though. Some sports medicine experts now recommend caution with anti-inflammatories in the first day or two after exercise. The inflammatory response is part of how your body repairs and strengthens muscle tissue, and suppressing it too aggressively may slow long-term healing. For garden-variety soreness, gentle movement and heat are worth trying before reaching for medication. Save the ibuprofen for when discomfort is genuinely interfering with your day.
Move Gently Instead of Resting Completely
This is counterintuitive, but light activity helps more than lying on the couch. Active recovery increases blood flow to sore muscles, flushing out cellular byproducts of exercise and helping tissue return to its normal state faster. Research from UW Medicine suggests that even six to 10 minutes of light activity at about 50 to 60 percent of your maximum effort can reduce inflammation and muscle breakdown.
What does 50 to 60 percent effort feel like? A leisurely walk, easy cycling, or gentle swimming. You should be able to hold a conversation without any strain. The goal isn’t to train. It’s to get blood moving through sore tissue. A short walk the morning after a hard workout can make a noticeable difference in how you feel by the afternoon.
Hydration and Electrolytes
Dehydration alone can cause muscle aches, cramps, and spasms. Your muscles depend on a balance of electrolytes to function properly. Sodium controls fluid levels and aids muscle function. Potassium supports muscle contractions. Magnesium helps muscles relax after contracting. Calcium plays a role in the signaling that tells muscles when to fire. When any of these drop too low, you can experience cramping, weakness, and persistent soreness that doesn’t seem connected to exercise.
If you’re sweating heavily, drinking plain water may not be enough. Adding an electrolyte drink or eating potassium-rich foods like bananas, potatoes, and leafy greens can help restore balance. Most adults need 400 to 420 mg of magnesium daily (men) or 310 to 320 mg (women), and many people fall short. Forms like magnesium glycinate and magnesium citrate are absorbed better than magnesium oxide. Epsom salt baths (magnesium sulfate) can help sore muscles feel better, but they don’t actually raise your body’s magnesium levels through the skin.
What About Protein and Tart Cherry Juice?
Protein is essential for muscle repair, but the timing and form may matter less than you think. A Harvard Health analysis of research found that high-protein drinks after resistance training didn’t reduce muscle soreness or speed recovery compared to a carbohydrate-only drink. The men in the study consumed 32 grams of protein post-workout and reported the same levels of soreness 24 to 48 hours later as those who drank only carbs. Getting adequate daily protein matters for long-term muscle health, but a post-workout shake isn’t a fast fix for soreness.
Tart cherry juice has gained popularity as a recovery aid because of its high concentration of anti-inflammatory plant compounds. Some research shows that consuming tart cherry concentrate for about a week before intense exercise can improve endurance performance and may reduce inflammation. But results are inconsistent. A 2023 study found that concentrated tart cherry supplements taken for eight days didn’t improve muscle soreness or function in recreationally active women. Doses and forms vary so much across studies that there’s no clear recommendation on how much to take.
The PEACE and LOVE Approach to Injuries
If your muscle aches stem from an actual injury rather than normal exercise soreness, sports medicine has moved beyond the old RICE method (rest, ice, compression, elevation). The current framework, published in the British Journal of Sports Medicine, is called PEACE and LOVE. It covers both the immediate response and the longer recovery phase.
In the first one to three days, protect the area by reducing movement enough to prevent further damage, but don’t immobilize it completely. Prolonged rest weakens tissue. Elevate the limb above your heart when possible to help drain fluid. Compress with a bandage or tape to limit swelling. Let pain guide how much you move.
After those initial days, shift to gradually loading the tissue. Gentle, pain-free movement promotes repair and builds tolerance. Start pain-free aerobic exercise like walking or easy cycling to boost blood flow to the injured area. Staying optimistic isn’t just feel-good advice: research shows that fear, catastrophizing, and depression measurably slow recovery from musculoskeletal injuries.
When Muscle Aches Signal Something Serious
Normal soreness is uncomfortable but manageable. It doesn’t change the color of your urine, and it improves over a few days. Rhabdomyolysis is a rare but dangerous condition where muscle fibers break down so severely that their contents leak into the bloodstream, potentially damaging the kidneys.
The warning signs that separate rhabdomyolysis from normal soreness include dark urine that looks brown, red, or tea-colored, combined with severe muscle tenderness, swelling, and weakness. Some people also experience nausea, decreased urination, or confusion. If you notice dark urine alongside unusual muscle pain, especially after an extreme workout, a crush injury, or prolonged heat exposure, get medical attention immediately. This is one situation where waiting it out can be dangerous.
