Yes I totally understand. I love spicy food. sigh...

Now I only eat bland "old lady" things...but you know I don't have the burning anymore either. So it is worth it IMO.!

I have started today not to eat night shades vegetables I will keep on that, I hope this will help to release the burning problem.
Do you have any idea after how long it should help?
I do not have diabetes, do you think sugar affects burning?

You don't have to have diabetes to have problems from sugar. I have very good glucose levels everytime I test. Home and reg. blood tests. Eating like a diabetic, not gluten, paleo type foods has been wonderful along with supplements. Refined sugar is never good.

I don't have diabetes either, but sugar does contribute to the burning. Wine is also a contributor--like I've said before, eating just isn't any fun any more!

Wine has sulfites in it... and these cause allergic reactions in some people.
Also the histamine content cause excessive vasodilation and this can be a burning trigger therefore IMO.

I have a histamine thread here:

This is one reason, I believe that AlkaSeltzer works, and also
Benadryl for some of us.

Unfortunately, if one is sensitive to histamine from foods, there will be MORE things one has to avoid!

The nightshade burning is pretty quick resolve I found.
The peppers especially and tomato. Potatoes however are sneaky and may flare you a day or two later. This makes it more difficult to make the link from what you ate earlier in the day, to the burning feet/legs at night.

Sugar, and especially fructose is also a common problem. It is estimated that 1 in 3 people have a genetic problem with fructose.

Nightshades:
http://en.wikipedia.org/wiki/Solanaceae
Solanine is thought to be the culprit from most of the nightshades. I've seen some mention that it can accumulate in the body, leading to further symptoms with time, if consumed regularly.
This small study found that solanine in potatoes lasted about 24 hrs in the body, and suggests a long term effect if consumed often.

Here is a site that goes into more detail:

I know I have a lot of allergies from hay fever to night shades (and also to cats). I did try that Histame that's mentioned in the article, but it didn't help me.

One day last Spring when both my youngest son and I were experiencing severe nasal symptoms, he brought over some Alavert (active ingredient Loratadine 10 mg) that the pharmacist had recommended to him. We both tried it and it works, but I didn't like the after-effects. Now I take 1/2 or even 1/4 tablet if I'm going someplace where they have a cat and that works for me. It may block the burning symptoms too, but when I've taken it, I've been more focused on my nose!

I also have had cataract surgery and most anti-histamines dry my eyes out too much, even the non-drowsy ones. Claritin never helped me al all.

Claritin (loratidine) has to be activated by the liver, because it is the active metabolite with the actions, not the parent drug.
This causes a delay of up to 3 hrs ... it is not fast acting.

I never liked Claritin.... I think it is useless!

This sounds like RLS (restless leg syndrome), not PN. I take Mirapex (AKA Pramipexole) for RLS - changed my life. I can sleep again!
