Muscle pain is extremely common—whether it's a steady ache or a stabbing pain in just one place or all over your body. It happens for several reasons: You may have worked out too hard, injured yourself, or have an undiagnosed condition. Nerve endings in your muscles and along your arteries transmit pain in response to inflammation, lack of blood flow, or mechanical force. Read on to learn what may be causing your pain and how to relieve it. Common Causes of Muscle Pain Muscle pain happens because of overuse, injury, stress, and tension, whether from an intense workout or hard physical work. In these cases, connecting the pain with the cause is easy. Other reasons like life stresses aren’t as easy to pinpoint. Here’s a look at a few of the more common causes of muscle pain. Delayed Onset Muscle Soreness (DOMS) Delayed onset muscle soreness (DOMS) refers to the pain and stiffness you feel after working out harder or longer than usual. Researchers used to believe it involved just the muscles, but a 2021 study suggests it involves fascia too. DOMS usually starts a few hours after your workout and peaks one to three days later. All kinds of exercise can cause DOMS, but exercises that involves eccentric contraction (when your muscles lengthen) is the most likely culprit. Some examples of eccentric contractions are: Lowering into a deep, weighted squatLowering a weight during a shoulder pressLowering your arm during a biceps curl Injury You can injure your muscle and connective tissue either directly, in one shot, or over many contractions, causing pain and stiffness due to damage and swelling. An injury in one limb may sometimes cause you to overcompensate with other body areas, leading to aches. An overuse injury, such as in sports, can also cause pain and weakness over time. Breaks and fractures can also lead to muscle pain. Infections A whole host of bacterial and viral infections can cause muscle pain. When your immune system is fighting a virus, it could leave you with muscle inflammation and weakness. Some bacterial infections that can cause muscle aches and pain include: Cold Flu Lyme disease Pyomyositis (rare) SARS COVID-19 Is Muscle Pain a Symptom of COVID-19? Stress and Tension Stress and tension affect all parts of your body and can have a profound impact when it’s chronic. When you’re stressed, you unconsciously tense up your muscles. Doing this many times a day can lead to pain (and tension headaches that hurt your neck and shoulders). Muscle pain in your lower back and upper body is especially linked to job stress. Muscle Cramps Muscle cramps are continuous, involuntary, and painful contractions of your muscle or part of your muscle. They're usually confined to one area (often the calf), although that doesn't mean the area is the source of your cramps. They can last for a few seconds to several minutes. Muscle cramps can be caused by: HeatExerciseElectrolyte disturbancesHormonal imbalancesNeurological conditions Medications Some medications may increase your chance of muscle aches and pains. One of the most cited classes of medication is statins, used to lower "bad" cholesterol. However, a 2022 study of 1,000 people using the medicines found that it was associated with only a small increase in mild-to-moderate muscle pain. Other medications, like dexmethylphenidate (prescribed for ADHD), can cause severe muscle pain and stiffness. If you haven't identified the source of your muscle pain, check your medications for side effects. What Medical Conditions Cause Muscle Pain? About 47% of the population experiences muscle pain at any given time. That said, researchers have found that some factors can put you more at risk for chronic or recurring muscle pain. They include: Older ageAnxietyBeing sedentary Some conditions can also cause chronic muscle aches and pain. Here’s a look at a few. Myofascial Pain Syndrome Myofascial pain syndrome is a chronic pain disorder. In this condition, pressure on sensitive points in your muscles (trigger points) causes pain in the whole muscle and sometimes in seemingly unrelated parts of your body, which is called referred pain. Sometimes the trigger points are activated without cause. Fibromyalgia Fibromyalgia is a chronic disorder that causes pain and tenderness throughout the body, as well as fatigue and trouble sleeping. It can cause a heightened sensitivity to pain throughout your muscles and other areas like your tendons and joints. If you have it, you may experience pain every day. Scientists do not fully understand what causes it, but it seems to be poor communication between your brain and body. It’s also related to depression, anxiety, and stress. Lupus Lupus is a chronic autoimmune disease in which your body attacks its own organs and systems. You can have flares when you get really sick and remission when you don’t have any symptoms. Muscle pain is often part of the condition. You’re most likely to feel pain in the thighs, upper arms, shoulders, and neck. Chronic Fatigue Syndrome This condition is also known as myalgic encephalomyelitis. Its hallmark symptom is severe fatigue after even mild activity, but muscle pain often shows up too. Researchers are still working to find the cause of the syndrome and how to treat it. Home Remedies for Muscle Ache It may seem counterintuitive, but using your muscles regularly can help prevent the causes of muscle pain. Staying in shape makes you healthier, helps you maintain and increase muscle mass, and helps prevent lifestyle diseases that can contribute to muscle pain. Here are some ways to help you feel better now: Over-the-counter (OTC) medications like Tylenol (acetaminophen), and non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin, Motrin (ibuprofen), and Aleve (naproxen) Heating pads for the affected part Ice packs to reduce swelling and numb the area Lidocaine patches or cream, which you apply on your skin to numb it Relaxation techniques like meditation, hot baths, or other relaxing activities For a sports injury, try PRICE (protect the part, rest it, ice it, compress it, and elevate it) Herbal Supplements You may have heard about OTC supplements and their use for muscle pain. However, little evidence exists to support their effectiveness in pain relief. Some also have potential side effects, so you're probably better off sticking with an OTC analgesic or another way of relieving your pain. A few small clinical trials support willow bark's usefulness for chronic low-back pain and osteoarthritis. Likewise, there is some support for omega-3 fatty acids' modest help with rheumatoid arthritis symptoms. Here are a few popular herbal remedies with little-to-no supporting evidence: Devil's claw Ginger Thunder God vine Turmeric Bromelain (pineapple plant) Important Facts About Non-Narcotic Pain Drugs Dietary supplements are minimally regulated by the FDA and may or may not be suitable for you. The effects of supplements vary from person to person and depend on many variables, including type, dosage, frequency of use, and interactions with current medications. Please speak with your healthcare provider or pharmacist before starting any supplements. When To See a Healthcare Provider See a healthcare provider if your pain is severe, long-lasting, or is accompanied by other symptoms like fever, excessive swelling, or problems moving an affected body part. A Quick Review Muscle pain is extremely common and will affect nearly everyone at some point. Activities like heavy lifting workouts, lifestyle factors like excessive stress, and chronic conditions can cause or worsen it. If your pain is moderate and isn’t long-lasting, try treating it at home. If it’s more intense or lasts a long time, see a healthcare provider for help and diagnosis. Was this page helpful?
