Fibromyalgia: Your GoodRx Guide

Comprehensive information for you or a loved one — including treatment options and discounts on popular medications.

Fibromyalgia affects about 5% of men and 8% of women in the U.S. It’s more common in people who have autoimmune conditions like lupus, but it can also occur by itself.

Living with fibromyalgia is challenging, and some days may be harder than others. This can feel discouraging. But there are many therapies that can help. The best treatments aren’t pills. In fact, they’re mind-body techniques and exercise. Sometimes, medications can help, too.

What are the signs and symptoms?

The most common symptom of fibromyalgia is widespread pain throughout the body. The pain can occur anywhere. But it most often occurs in the:

  • Neck

  • Upper back

  • Chest

  • Buttocks

  • Lower back 

Pain might feel sharp, achy, burning, or tingly. It typically affects many areas of the body at once, not just one. 

In addition to pain, other common fibromyalgia symptoms include:

  • Stiffness of the joints and muscles

  • Tenderness of the body to light touch

  • Trouble falling asleep or staying asleep

  • Fatigue and exhaustion (despite getting enough sleep)

  • Brain fog,” which might include trouble with memory, finding words, concentration, and/or slowed thinking

  • Trouble with body temperature (feeling too hot or too cold)

  • Body swelling

People with fibromyalgia commonly have other health conditions, too. Examples include:

  • Depression and/or anxiety

  • A history of trauma (physical or emotional)

  • Migraines

  • Irritable bowel syndrome (IBS)

Causes

Scientists don’t know exactly what causes fibromyalgia. But they believe that many different factors contribute to it. Women are more likely to get fibromyalgia than men, but anyone can get it.

As a central sensitization syndrome, the brain plays a big role in fibromyalgia. Studies show that in people with fibromyalgia, the brain processes pain differently. You might think of it like cranking up the volume on a radio. In fibromyalgia, the brain makes pain signals louder. That’s why touch that normally doesn’t feel painful can feel painful for people with fibromyalgia. 

Certain genes (what we inherit from our birth parents) also increase the risk of developing fibromyalgia. That’s why people who have close relatives (parents or siblings) with fibromyalgia are more likely to get it. The idea is that some people have a genetic predisposition to high pain sensitivity. When they are exposed to stressful life triggers, fibromyalgia occurs. This could include physical stress, such as infection, inflammatory disease, or injury. Or it could include emotional stress, like harmful childhood experiences. More research is needed to confirm this theory.

How do you test for fibromyalgia?

Unfortunately, there is no single test to diagnose fibromyalgia. Providers use a combination of symptoms and physical exam to diagnose it. Symptoms must be present for at least 3 months. Blood tests or imaging are typically not necessary for diagnosis. Sometimes they may be ordered to rule out other conditions, though.

The American College of Rheumatology has developed criteria that help providers diagnose fibromyalgia. These include a variety of questions about the location and severity of pain, as well as other symptoms.

Treatments

There might not be a cure for fibromyalgia, but there’s hope. There are a lot of treatments that can help decrease pain and fatigue, improve quality of life, and improve level of function.

Non-medication therapies are offered first because studies show they work. Options include:

Stress reduction and getting more sleep may also help relieve symptoms. More on this below.

Medications

If non-medication therapies aren’t enough, medications may reduce pain by about 30% in some people. But they are not likely to help if used alone. In other words, they work in combination with the treatments listed above. FDA-approved options include:

Other medications that aren’t FDA-approved may be prescribed off-label (using a medication for a different condition than what it was approved for). These include:

Studies have shown that the following medicines do not help:

Living with fibromyalgia

It’s common to experience anxiety or depression when you live with severe pain every day. And this can make the physical pain feel worse. With help from a mental health specialist, medications and talk therapies can improve both your mood and the pain. 

Lifestyle habits also play an important role in mental health and fibromyalgia. For example, sleep quality, lowering stress levels, and education about fibromyalgia are all important when it comes to feeling your best. Yoga and acupuncture may help, too.

Common concerns

What conditions can be confused with fibromyalgia?

Several different conditions may cause widespread pain. Examples of these are rheumatoid arthritis and lupus. This is one of the reasons that getting a diagnosis of fibromyalgia can be tricky. Your healthcare provider may or may not suggest additional tests to rule out other conditions. But at the end of the day, you know your body best. So don’t be afraid to speak up in order to get the answers you need.

Does CBD oil help fibromyalgia?

Maybe. More studies are needed to know if cannabidiol (CBD) helps fibromyalgia.

Does fibromyalgia cause weight gain?

No. Fibromyalgia doesn’t cause weight gain, but some people feel like their bodies swell during fibromyalgia flares. Also, medications like pregabalin and gabapentin may cause weight gain in some people. 

What foods should you avoid if you have fibromyalgia?

Currently, there is not enough evidence to recommend a specific diet for people with fibromyalgia. However, some people notice that certain foods make their symptoms worse. It can help to keep track of your diet and changes in your symptoms. If you identify a “trigger food,” you could consider avoiding it to see if you feel better.
