I have a dry very irritating cough for about 2 weeks. No apparent reason except low B12 can cause and neuropathy can cause irritation to lungs. Is there anything neuropathy doesn't make worse? It is the most frustrating and debilitating disease without a treatment. I do take a spin off new supplement to Metanyx called EB-N6. Prescribed by my podiatrist; the only doctor who has really helped me. I have ideopathic neuropathy not diabetic but my doc said it is an improvement over metanxy and provides you with the correct amounts of B6 and B12. Twice a day with food. I take no other B supplements so I am not overdoing the B6 or 12. Anyone else have a cough? I haven't gone to Urgent care or primary but I will since it is not a cold or upper respiratory. Guess I should have a chest X Ray.
