This is a neurotransmitter imbalance disease. See below for explanation.

In my experience, the most effective approaches to treating fibromyalgia are amino acid supplementation according to the protocol developed by Dr. Hinz and homeopathy. The choice of therapy depends on the patient’s preference. Both are very effective and can be used in conjunction in some cases, but should be started one at a time to be clear of the effect of each approach. Before starting a particular therapy I like to make sure the patient understands the pros and cons of both and can make an intelligent decision.

The following article can be read in its entirety on Dr. Hinz’s site.

The NeuroResearch approach is achieving 100% relief of fibromyalgia symptoms.

At times a physician will ask about other fibromyalgia treatment approaches to enhance outcomes. You can't get relief better than 100% with fibromyalgia. NeuroResearch Clinics sees no need to add things to fibromyalgia treatment protocols. Optimization of serotonin and dopamine in fibromyalgia reveals no reported treatment failures since 2002. Patients with fibromyalgia typically have 3 or more other neurotransmitter diseases active simultaneously. Other approaches to fibromyalgia treatment need additional treatment for these diseases whereas the approach of NeuroResearch Clinics essentially "pushes the right button" for relief of all these diseases with one approach. This is Fibromyalgia treatment at its best with no drugs or drug side effects.

Fibromyalgia Treatment: Arthritis and Rheumatism. Vol. 33, No. 2 (February 1990)

Fibromyalgia is a distinctive syndrome which can be diagnosed with clinical precision. It may occur in the absence of other conditions known as primary fibromyalgia. It may be in the presence of other conditions such as rheumatoid arthritis or systemic lupus erythematosus known as concomitant fibromyalgia. It is rarely secondary to another disease, in the sense that alleviation of the associated disease also cures fibromyalgia. With widespread musculo-skeletal pain and multiple tender points the diagnosis of fibromyalgia may be confidently made.

The American College of Rheumatology 1990 Criteria for Fibromyalgia Classification.

Fibromyalgia Treatment: History of widespread pain has been present for at least three months.

Definition: In fibromyalgia treatment pain is considered widespread when all of the following are present:

• Fibromyalgia pain in both sides of the body.

• Fibromyalgia pain above and below the waist In addition, axial skeletal pain (cervical spine, anterior chest, thoracic spine or low back pain) must be present. Low back pain is considered lower segment pain.

Fibromyalgia

Pain from fibromyalgia in 11 of 18 tender point sites on digital palpation:

Definition: Fibromyalgia pain, on digital palpation, must be present in at least 11 of the following 18 tender point sites:

• Occiput (2) - at the suboccipital muscle insertions.

• Low cervical (2) - at the anterior aspects of the intertransverse spaces at C5-C7.

• Trapezius (2) - at the midpoint of the upper border.

• Supraspinatus (2) - at origins, above the scapula spine near the medial border

• Second rib (2) - upper lateral to the second costochondral junction.

• Lateral epicondyle (2) - 2 cm distal to the epicondyles

• Gluteal (2) - in upper outer quadrants of buttocks in anterior fold of muscle.

• Greater trochanter (2) - posterior to the trochanteric prominence.

• Knee (2) - at the medial fat pad proximal to the joint line

In diagnosing fibromyalgia digital palpation should be performed with an approximate force of 4 kg. A fibromyalgia tender point has to be painful at palpation, not just "tender."

I have treated numerous people with fibromyalgia using NeuroResearch method and have seen very good results.
Let’s discuss the pros and cons for using the NR method and homeopathy.

NeuroResearch amino acid supplementation

Pros:

• Fast:  good improvement is usually seen within 4-6 weeks of starting the therapy, often faster.
• Very simple to use: the same protocol is used for everybody and the only adjustment is in the dose of the supplements.
• Predictable: most people respond well.

Cons:

• Non-curative: you are better only as long as you continue to take the supplements.
• Many pills to take.
• Supplements are more expensive in the long run than successful homeopathic treatment.

Homeopathy

Pros:

• Curative: you take the remedy only as long as necessary, with the goal of permanent alleviation of symptoms and eventually stopping the remedy.
• Treats all symptoms at the same time, not just those related to the neurotransmitter imbalance.
• No large numbers of pills to take.
• Less expensive in the long run: the remedy is included at no charge, you pay only for the doctor’s time.

Cons:

• Much more difficult in practice.  The visits take a lot more time and effort on the part of the doctor, because the treatment is highly individualized.  That is why the first visit for homeopathic treatment is much more expensive than the one for NeuroResearch treatment.  Also, insurance coverage for the homeopathic visits is usually not as good as for the NR visits.
• The effect is often quite slow.  Sometimes it takes more than one try for the doctor to find the effective remedy.  Until one is found, there is no effect.  Once the correct remedy is found, the effect is usually slow.
