It is frustrating to not know the cause of neuropathy in many cases. As you are aware, idiopathic means no known cause. Idiopathic neuropathy has existed long before vaccines, so you may never know the cause unfortunately. However, I understand your hesitancy to get the new 2023 COVID vaccine for fear of making things worse.

This would be a good discussion to have with your doctor and/or neurologist. They can talk about the potential risk factors for you specifically based on your medical history.
