Had small fiber neuropathy (I suspect a SCN9A defect which produces hyperexciability). Took Pilocarpine which eliminated tachycardia and altered bowel and bladder motility. Have connective tissue defects: Diverticulitis requiring bowel resection, stage 3-4 hemorrhoides, hiatial hernia, eosinophilic eosaphagitis, vericose veins, dry mouth - gingivitis requiring repair of gum-line carries in all teeth, frozen shoulder, etc. Traced this to muscarinic receptor neuropathy. What can I do to reverse neuropathy? Eric
