Pain all over the body is usually systemic muscle pain and is often the result of an illness, infection, drug side effects or fibromyalgia, reports Mayo Clinic. Influenza and Lyme disease are two illnesses that cause muscle pain.
Body aches are a common symptom of viral infections, such as the common cold and the flu. The pain manifests as muscle aches, tenderness and cramps, according to Everyday Health. It also appears as joint pains, joint stiffness, neck and back pain. Treatments for overall body pain depend on the severity of the pain and the cause of it. Treatments include over-the-counter medications, such as acetaminophen; warm baths; and a massage.
Fibromyalgia is a disease that affects the body's muscles and tissues. The most common symptom of this disorder is widespread pain, states WebMD. The individual feels this pain all over the body, and it can be deep, dull, sharp or throbbing. The pain may travel throughout the body. People with fibromyalgia also suffer from tenderness around the joints.
Other symptoms of fibromyalgia include sleep problems and numbness in various parts of the body, notes WebMD. Many people with fibromyalgia have morning stiffness, which occurs when the muscles and joints are very tight when first waking up and need stretching and loosening before engaging in everyday activities.
