Can chronically low cortisol ever be the cause of neuropathy / parasthesia / muscle weakness . all over body?

These paresthesia and neuropathy are not the usual symptoms of low cortisol but muscle weakness is definitely present . These sensory loss may be due to low cortisol. Get checked for B12 and folate deficiency. Also pathology behind low.cortisol can also cause neuropathy. Hope it helps.

Typically low cortisol levels are associated with muscle weakness which can be all over the body. True neuropathy and/or paresthesias may represent another condition and should be evaluated and treated by an appropriately trained provider.

Elevated steroid levels can cause weakness secondary to direct effect on Type II muscle fibers, and low bodily steroids cause weakness secondary to general inanition, fatigue, and muscular deterioration. High or low steroid levels do not cause peripheral neuropathy, but the underlying endocrinopathy may be a culprit. See and endocrinologist and get this handled.
