Most of the symptoms you reported (muscle weakness, chronic fatigue, headache, mood swings, poor concentration/memory, numbness/tingling in extremities and face, lower back pain, stomach pain, dizziness, painful cycles, decreased desire for food) are subjective and cannot be measured. However, they all might be related to a neurological issue. For example, the lower back pain and the frequent urge to urinate might be related to a spinal column disorder or a spinal disorder itself (spinal deformity, discus hernia).


The muscle spasms (especially if found in the extremities) might be related to spinal column problems or the cause might be situated in the brain.
Nonetheless, the symptoms are not specific enough for a definitive diagnosis to be given.


You might want to visit a neurologist for a physical examination, an x-ray of the spine for possible discus hernia, a CT scan for possible disorders located in the brain, and evoked potentials to evaluate the speed of the impulses via the nerves to try to find the cause for the muscle spasms. Having in mind your family history (two grandmothers with Multiple sclerosis and a relative with Tay-Sacchs disease-both conditions affecting the neuromuscular system) specific genetic tests and additional tests might be needed.
