Dear John, I thank you very much for your warm welcome and for sharing your journey with neuropathy and important resources to help me. I will read and learn from them. I am a little hesitating about skin biopsy because I fear more pain from the wounds and I cannot take many pain medication during healing due to my current stomach issue. Regarding side effects, I did report my symptom to VAERS in 2021. I hope my voice was heard. Thanks again!
