Fibromyalgia Flashcards
Facts about fibromyalgia diagnosis:
- Pretty high prevalence (10-12%) for widespread, unexplained pain
- bilateral extremity, axial widespread pain, excessive point tenderness in 11/18 defined points
Wince in pain with just a bit of pressure; HIT WITH A HAMMER!!
Criteria of diagnosing fibromyalgia:
- Certain score of widespread pain index (above and below the waste)
- Symptoms present at similar level for at least 3 months
- Patient without disorder that could otherwise explain pain: neuropathic condition, psychiatric condition, med SE’s, etc.
Symptom severity score:
measures items outside of pain:
- fatigue
- waking unrefreshed
- cognitive symptoms
PE and labs:
- Look for musculoskeletal abnormalities; check ROM, strength, reflexes, then ask and palpate tenderpoints;
- Consider SLEEP EEG: you’ll see alpha waves in stage four mixed with the normal delta waves; less GH release!!
- Think maybe lyme or syphilis; maybe lupus based on LABS
Most frequent symptoms?
Muscle pain, fatigue
Etiology of fibro:
- abnormal serotonin pump gene, COMT as well (NT’s not around)
- HPA and ANS abnormal
- Lower pain threshold, abnormal brain imaging, increased CSF substance P;
Reflex symp dystrophy or sensitization: initial real physical injury allows remodeling of pain and sensation fibers, or dysfunction of NE/SR spinal pathways allows for crossed wires
Somatic depression: sad and weepy people who have more bodily pain and medical symptoms!!
Education:
- Let people know they have it: won’t increase morbidity, symptom reporting, disability claims
- educational groups can improve outcomes: improve pain, sleep, QOL, fatigue, self-efficacy, 6 min walk
Exercise:
- Cardio
- aquatherapy, aerobic exercise, tender points
- do 20 weeks: high intensity exercise to improve fitness
CBT is
helpful, could reduce pain severity and general functioning; meditation, relaxing, stress management help!!
Multidisciplinary:
CBT + education + exercise (+ biofeedback)
Meds:
- TCA
- SSRI (help pain, fatigue, depression, NOT tender points!!)
- SNRI: duloxetine and milnacipran (can raise NE as well as SR): BETTER THAN SSRI!!
- Tramadol (synthetic opiate) with SNRI and glutamate dampening, but LAST RESORT
- Carbamazepine
- Gabapentin (Ca channel blocker)
- Pregabalin (block Ca channels in pain fibers, decreasing ascending pain signals from the spinal cord)
If one develops depression or FM, more than likely
the Reticular activating system is sub optimal in that it does not feed or produce enough NE for example. Patients can be tired, fatigued, cognitively impaired- all as overlapping symptoms.
Normally, would help us think clearly, problem-solve, and be creative
NE pathways
descend upon and dampen the pain signals heading towards the brain; with enough NE tone, many pain signals do not get to the cortex to be interpreted as pain!!
With excess Ca and Na influx, AND excessive pain fiber firing and glutamate release
synapses become better integrated and fire more often; they are sens to fire with smaller painful stimuli or bodily sensations
