People with ME/CFS have fatigue that is very different from just being tired. The fatigue of ME/CFS:

• Can be severe.
• Is not a result of unusually difficult activity.
• Is not relieved by sleep or rest.
• Was not a problem before becoming ill (not life-long)

Worsening of ME/CFS symptoms after physical or mental activity that would not have caused a problem before illness. This is known as post-exertional malaise (PEM).

Sleep problems.

Many but not all people with ME/CFS have other symptoms.

Pain is very common in people with ME/CFS. The type of pain, where it occurs, and how bad it is varies a lot. The pain people with ME/CFS feel is not caused by an injury. The most common types of pain in ME/CFS are:

• Muscle pain and aches
• Joint pain without swelling or redness
• Headaches, either new or worsening

Some people with ME/CFS may also have:

• Tender lymph nodes in the neck or armpits
• A sore throat that happens often
• Digestive issues, like irritable bowel syndrome
• Chills and night sweats
• Allergies and sensitivities to foods, odors, chemicals, light, or noise
• Muscle weakness
• Shortness of breath
• Irregular heartbeat

Myalgic Encephalomyelitis does not have a cure.

Find a Dr or Consultant who listens to you is the first step

It is a manageable condition and depending on the severity of your symptoms the more difficult this can become.

I advise learning to listen to your body and what it is telling you. If you feel tired rest and if you feel pain find a solution to reduce that pain, this could be through pain medication prescribed by your Dr.

I am not saying that finding a Dr who listens or listening to your body is going to be easy as this illness is incredibly complex for some and manageable for others.

Having a Dr who listens to you or reads about the latest drug that sufferers are recommending can take a lot of unnecessary stress and anxiety from the sufferer.

It would be best for me to point you to the above question What is Myalgic Encephalomyelitis? 

Most pages list the illness as ME/CFS or Myalgic Encephalomyelitis/Chronic Fatigue Syndrome or sometimes even Systemic exertion intolerance disease (SEID).
