Wondering if your GABA blood levels checked? Also I have similar experience and neurologist diagnosed STIFF PERSON SYNDROME.
Hello Dear,
You probably have Benign calf amyotrophy.
Benign calf amyotrophy is a variant of the benign focal amyotrophy disorders. The etiology for these disorders is unknown
The gastrocnemius weakness and wasting were bilateral.. Initial progression of symptoms is followed by disease stabilization. No history of poliomyelitis or family history of neuromuscular disease. Creatine kinase values are elevated. The electromyographic and muscle histopathologic findings are consistent with a chronic neuropathic disorder. Despite the restricted calf muscle involvement clinically, the electromyographic abnormalities suggested more diffuse lower limb involvement.
The benign focal amyotrophy disorders are a clinically heterogeneous group of disorders causing weakness and atrophy of the upper or lower extremities.These disorders are distinguished from other more common forms of motor neuron disease by the restricted limb involvement, absence of upper motor neuron signs, and slow progression for months to years followed by disease stabilization
The criteria for the diagnosis is insidiously progressive unilateral or bilateral calf muscle atrophy or weakness, no known antecedent injury, (3) no sensory symptoms, no known medical or neurologic disorders that could cause muscle weakness or atrophy, no magnetic resonance imaging evidence of L5 or S1 nerve root disease.
ALS does not seem to be your diagnosis.You should consult your physican and aim at the treatment of Benign calf amyotrophy.
