The clinician is often frustrated when treating FS patients since symptoms are
Numerous and solutions inadequate. The finding of a potentially reversible
Problem (i.e. Mg deficiency) in some FS patients is encouraging. This study, as
Well as a previous report , identified a subgroup of FS patients that may
Benefit from Mg supplementation. More importantly, this finding may inspire
Further investigation into other easily treated problems that may cause FS
Patients difficulty. For a disorder such as FS which has no cure, the correction
Of any other problem which may be an exacerbation or perpetuating factor may not
Only be of help to the patient but may be critical in getting the FS under
Reasonably good control. There is certainly precedent for such reasoning.
Travell and Simons  have maintained for many years that MPS sufferers cannot
Be treated adequately unless perpetuating factors such as vitamin deficiencies,
Electrolyte imbalances, poor posture, etc. Are eliminated or ameliorated.
The question of whether Mg deficiency is pathogenic or simply an epiphenomenon
Is not known and requires further study. However, to he able to identify a
Correctable problem in FS sufferers is certainly desirable. Thus, Mg deficiency
Should be considered in FS patients especially if they are not responding to
Conventional treatments [15, 16] as expected. It is important to note that the
Mg deficiency in FS patients was discovered only when RBC Mg levels were
Measured. Thus, FS patients who are suspected of suffering from low Mg must be
Tested for both RBC and plasma Mg before Mg deficiency can be ruled out.
Many FS patients suffer from Mg deficiency. While the former condition can
Be treated but not cured and the latter is potentially corrigible, it is
Important to assess Mg levels in all FS patients for optimal management of their
