When trying to reveal a PN trigger, it is often useful to keep a journal of your days. What you ate at each meal, activities and exposures to toxins (golf courses, solvents, gardening chemicals etc). Food intolerances can cause PN symptoms... nightshade veggies can be a big culprit. (potatoes, tomatoes, peppers). Paprika and hot sauces, are part of the nightshade family.

MSG in processed foods can stimulate NMDA pain receptors.

Consider getting B12 measured. You should be at 400pg/ml or above. Lab ranges today are outdated still and report normals in the 200 range.

Sometimes the DNA mutations in methylation chemistry in the body will cause nerve damage. Getting this DNA testing may reveal a genetic error of metabolism for you.

None of the above are reliably targeted by doctors, but they are real issues that occur in people daily.
Your journal may reveal your trigger. We have had males
come here with hand issues that traced to overuse during exercise. (hands from weight lifting or push ups and feet from excessive running or bad shoes). Tying shoes too tightly, and wearing tight watches can compress nerves as well.

In regards to your alcohol symptoms, it may be that you are low in B1..which is thiamine.
Some people are genetically not able to handle alcohol because of this, and so they have symptoms with this problem. B1 also handles carbohydrates as well. So sugar and carbs may
cause PN symptoms due to poor metabolism. When you read here you will see some people posting about benfotiamine ( a longer acting B1 type) helping them. This supplement really began in Europe and at one time was very expensive. But now it is affordable and commonly available in US.
Trying a paleo type (low sugar and carb) diet may change your symptoms, and a journal would show that for you.
