Possible causes include a sprain or strain, an infection, medication use, and bites or stings. Muscles stiffness can also be accompanied by pain, cramping, and discomfort. It is usually not a cause for concern and can be treated with home remedies and stretching.
Stiff-person syndrome (SPS) is a rare, progressive neurological disorder. Symptoms may include: Stiff muscles in the trunk (torso), arms, and legs. Greater sensitivity to noise, touch, and emotional distress, which can set off muscle spasms.
There may be several reasons why your muscles are always tight. The most common reasons are dehydration, poor sleeping positions, muscle weakness, and muscle inhibition.
"But, if you have localized pain that is sharp, limits your mobility, changes your gait, affects your range of motion or is accompanied by significant weakness, it could be a sign of a serious injury that needs treatment."
Magnesium contributes to flexibility and helps to prevent injury by loosening tight muscles. Without enough magnesium, muscles can't properly relax, possibly causing cramps. Low magnesium can create a buildup of lactic acid, known to cause post-workout pain and tightness.
Sometimes muscle pain can linger for months. Muscle pain can be felt almost anywhere in your body, including your neck, back, legs, arms and even your hands. The most common causes of muscle pain are tension, stress, overuse and minor injuries.
Spasticity is stiff or rigid muscles. It may also be called unusual tightness or increased muscle tone. Reflexes (for example, a knee-jerk reflex) are stronger or exaggerated. The condition can interfere with walking, movement, speech, and many other activities of daily living.
Fibromyalgia can make you feel stiff. The stiffness may be most severe when you have been in the same position for a long period of time – for example, when you first wake up in the morning.
Myotonia occurs when your muscles aren't able to relax after they contract. Genetic changes usually cause myotonia, which can appear at birth or any age. Symptoms vary depending on the type of myotonia. You can manage symptoms with lifestyle changes, medications, supportive devices and physical therapy.
Autoimmune disorders that specifically affect the muscles, joints, and nerves include rheumatoid arthritis (RA) and multiple sclerosis (MS). Polymyalgia rheumatica, which also involves the joints, is thought to be an autoimmune condition, according to the Arthritis Foundation.
But, though it's rare, those muscles can sometimes rebel against us. Stiff Person Syndrome (SPS) is an autoimmune and neurological disorder that can make the muscles in the torso and limbs alternate between rigidity and spasms. The cause of this extremely rare disease is still unknown.
Suxamethonium (succinylcholine)
At a dose of 1 to 1.5 mg/kg, suxamethonium causes extremely rapid muscular paralysis, and optimal intubating conditions are obtained within 30 to 60 seconds.
Metaxalone
Taken as 800 mg tablets 3 to 4 times a day, metaxalone (Skelaxin) has the fewest reported side effects. It's also the least likely of the muscle relaxants to make you sleepy. It may work better for chronic lower back pain that is flaring up, rather than for pain that is new.
Traditionally succinylcholine has been the most commonly used muscle relaxant for this purpose because of its fast onset and short duration; unfortunately, it can have serious side effects.
“This is one of the rare circumstances where the more it hurts, the more you need to do it,” says Biggart, noting that frequency—not intensity—is key. “Roll your tight muscles a minimum of once a day for 10 days to two weeks, or until you feel relief,” says Biggart. “Two to three times a day is even better.
Chronic muscle tension may increase your risk of heart disease. When the muscles remain in a constant state of tension, blood pressure rises, placing additional stress on arteries, blood vessels and organs. Subsequently, this can lead to stroke or other serious heart disease.
Fibromyalgia is diagnosed based primarily on having pain all over the body, along with other symptoms. Currently, there are no specific laboratory or imaging tests for fibromyalgia.
Magnesium malate relieves muscle tension by relaxing tense areas. It is for this reason it is so effective at helping to ease muscle spasms. It also supports hundreds of enzyme processes inside the body, and helps the cells in your body produce and use energy.
