Your body contains over 600 muscles. When one or more of them hurt, it can be hard to concentrate at work, focus at home or function in everyday life. Instead of simply tolerating muscle pain (myalgia), learn what it may mean so you can treat it and feel better.
What Causes Muscle Pain?
Myalgia can occur after overusing muscles while working, exercising or playing. Certain medications, including ACE inhibitors for blood pressure and statins for cholesterol, may also trigger muscle pain.
Sometimes muscle pain has no clear activity-related cause and may signal an underlying condition such as the flu, hormonal imbalance, vitamin D or B12 deficiency, or infections like hepatitis, Lyme disease or parasitic infection. Autoimmune conditions such as lupus or multiple sclerosis can also cause muscle pain.
What Does Muscle Pain Feel Like?
Myalgia can present in several ways depending on the cause and the affected muscles.
- Pain in one area or in multiple areas of the body
- Dull, sharp, intermittent or constant pain
- Ongoing pain even at rest
- Muscle twitching or painful cramps
- Numbness, tingling or burning sensations
- Associated joint pain
What are the Complications of Muscle Pain?
Most muscle pain improves with self-care, but certain signs may indicate a more serious problem that requires medical attention.
- High fever
- Shortness of breath
- Difficulty swallowing
- Unexplained water retention
- Inability to move part of your body
- Severe muscle stiffness
- Muscle atrophy (loss of muscle mass)
When Should You Seek Medical Help?
You can often treat muscle pain at home with rest, over-the-counter pain relievers, topical treatments and gentle exercise, but see a doctor if certain conditions occur.
- Pain that persists for more than three days
- Severe or worsening pain
- Signs of infection such as fever or spreading redness
- Any swelling, redness or rash around the muscle
- If you make changes to the dose of blood pressure or cholesterol medication because of muscle symptoms
How Can You Prevent Muscle Pain?
Preventive steps include proper warm-up and cool-down when exercising, stretching before rigorous activity, avoiding staying in one position too long, and maintaining regular physical activity to keep muscles strong and flexible.
