Fibromyalgia

Matt’s Recovery [2:39]

Fibromyalgia – One form of amplified musculoskeletal pain (AMP) is diffuse pain that involves at least 3 major body parts for longer than 3 months. Frequently this involves all or almost all of the body. There is also other criteria for diagnosis in children which requires multiple other symptoms such as sleep disturbance, weather sensitivity, abdominal pain, etc. The adult criterion for diagnosis of fibromyalgia is five painful and tender points. The old criteria for a diagnosis of fibromyalgia required that 11 of 18 tender points be painful when pressed upon. That tender point count, and now, requirement to have widespread pain is quite typical of diffuse amplified pain in children.

Although these children are diagnosed as fibromyalgia we do not find that to be a helpful term for patients since children respond so well to these amplified musculoskeletal pain syndrome programs. It seems that adults diagnosed with fibromyalgia have a poorer prognosis, however, they are not treated in the same way that we recommend children be treated so we do not know how they would respond to a program like the one detailed in the video. 65-70% of the children treated by the AMPS team shown in the video have diffuse amplified pain or fibromyalgia.

Children with diffuse amplified pain can have multiple amplified body sensations including feeling lightheaded and dizzy, abdominal pains, breathing difficulties, urinary symptoms, visual disturbances, chest pains and racing hearts, to name a few.  Disturbed sleep has been described in many studies of fibromyalgia with an increase of alpha Delta sleep during sleep studies. In the children we studied, they indeed had an increased amount of alpha Delta sleep but after going through a treatment program they resolved their pain and slept well, yet there was no change in the amount of alpha Delta sleep they had. By far the vast majority of children to complain of sleep disturbance do not fall asleep during the day or at school so the health professionals on the pain team at Children’s Hospital of Philadelphia feel strongly that treating sleep with medication is generally counterproductive.

There may be a genetic component since fibromyalgia can be found in multiple family members. Since most who suffer from fibromyalgia are female, there may be hormonal influences as well. Depression, anxiety and other psychological issues are common in people suffering from fibromyalgia or diffuse amplified pain and need to be assessed and appropriately addressed. Some, but not most children, may require medication to help stabilize their mood or help with anxieties.

Amplified musculoskeletal pain is all-encompassing term that includes fibromyalgia, myofascial pain, diffuse amplified pain, complex regional pain syndrome (CRPS), localized amplified pain, etc. and there’s also a group of children who have intermittent amplified pains. There is a great deal of overlap between these subtypes. For instance, a child can have a cool blue hand with CRPS and then have a very painful leg that is not cold or blue so would be localized amplified pain or they may have total body pain so they would have CRPS and diffuse amplified pain or fibromyalgia. Likewise some children will have CRPS, go into remission, and then later develop total body pain. It’s all part of the spectrum of the amplified pain syndromes. We believe the mechanism of the pain is the same, that is increased activity of the autonomic nerves causing decreased blood flow and leading to ischemic pain. The pain is very real and very much in the child’s body, but it is not biologically damaging. We’ve all heard the squeal from a speaker when a microphone gets too close to it. Although the sound going into the microphone is soft, it comes out the speaker and then goes back into the microphone and then out the speaker again setting up a vicious cycle and becoming intolerably loud. In amplified pain a very soft signal, such as a light touch, can short-circuit across the nervous system to cause autonomic firing and then decreasing blood flow which then leads to more pain and thus the vicious cycle is set up. A very light touch is thereby amplified to an intolerable pain. In order to effectively break the cycle we can retrain the nerves by exercising and desensitizing the child to the pain seemingly resetting these nerves. This is similar to scar desensitization; when one has a painful scar one has to rub it vigorously as much as possible in order to settle down the nerves so that it stops being so painful. Just touching the scar lightly a couple of times a day will never adequately desensitize.

Although the treatment varies from child to child depending on their pain and individual needs, the principle is the same and that is that the child essentially cures him or herself by exercising and desensitizing through it. After going through an AMPS program, a very small percentage of AMPS patients return to the program, but the vast majority are empowered to address future pain themselves. Once they are in remission they can stay in remission using the tools they learn in the program should they have any inkling of a reoccurrence.

Since this pain is so intense and misunderstood and since many friends, neighbors, teachers and physicians do not believe these children have as much pain as they do, the children can be accused of faking or lying. That in itself is quite distressing. The pain not only controls the child but it controls the whole family and that control needs to be directly addressed and stopped. Just as the child has to use her mind to walk on a painful foot the family has to let go and let them walk on the foot without worrying that every new pain is a fracture or symptom a catastrophic illness. Counseling can serve in multiple ways. It can help the child learn coping skills to deal with the pain as they are increasing their bodily function. It can also help them identify stressors in their life and deal with them more constructively. Additionally, it can help the family assess how the family communicates—either appropriately supporting the child or reinforcing the pain or sick role so that that can be identified and addressed. There is a term “secondary gain” which means the benefit one receives from their illness or distress. Even though I am quite miserable when I have the flu it feels good to have my back rubbed and have hot chocolate brought to me. Even if you are a stellar student there is some secondary gain to not going to school and not having to keep up academically. It’s also stressful to be missing that schoolwork so it’s a real two-edged sword.

Conversion

It is not uncommon for children with amplified pain to have conversion symptoms. These are symptoms that arise when the subconscious mind converts feelings and emotions into bodily feelings or movements. Conversion symptoms by definition do not hurt. They include such things as conversion spells (previously known as pseudoseizures), paralysis of part of the body or the entire body, blindness, deafness, shaking, dizziness, memory loss, urinary symptoms such as urgency or retention, breathing and swallowing difficulties such as feeling a lump in ones throat all the time to name a few. The classic example of a conversion is when a person witnesses something horrific and then they go blind. Their eyes and brain work just fine but emotionally they cannot accept any visual information and so they are functionally blind. This needs to be addressed with counseling but we also want to limit, as much as possible, any secondary gain from the conversion symptoms. So even if one goes blind they have to go to school and regular family activities continue normally.

Self-Injury

Children with amplified pain are prone to self-injury. The pain is so desperate sometimes an injury such as bruising or cutting oneself gives some form of relief, as strange as that may sound. This is an additional manifestation of the psychological distress the child is feeling and needs to be addressed with counseling.
