I'm glad to hear that you are doing well and that you have given up smoking. I gave up last year but started again to help a stressfull situation. I am going to try and quit again at some point...

Now, tyrosine also has to be provided as a precursor.

There are just global effects of low Vit D coming forth in the press and
in research. The Vitamin D Council has many papers.

About 3 months ago my Vit D levels were less than 2, this is the second time this has happened last time they were 8 though, I took 50,000 uints once a week for 8 weeks.....and then I got kidney stones! Sheesh.

I have been reading about Vit D deficiencies and wondering if there may be a connection with my "idiopathic small fiber PN". Although I did have a skin punch biopsy that showed small fiber abnormalities in my hip and ankle. I wonder if this is still a possibility? I do have decreasing bone density in my painful toes. And I'm only 31.

Thanks everybody for the good info.

--just an opinion, though I like to think it's an informed one--is that Vitamin D deficiency alone will not result in peripheral neuropathy, particularly small-fiber neuropathy, although Vitamin D deficiency may result in calcium malabsorption, and low calcium levels to lead to parasthesas ("strange sensations") in nerve--tingling, stinging and the like.

If one is low in Vitamin D--and one certainly can be, especially in higher latitudes during colder times of the year--a thorough work-up for other vitamin/mineral malabsorption should be done: B12, B6, Calcium, Magnesium--especially if there are neurological symptoms. Some deficiencies of this type--especially of the B-vitamins--can lead to neuropathy, and there is also the possibility of gastrointestinal malabsorption syndromes such as IBS, Crohn's, or celiac/gluten sensitivity. The latter two, inasmuch as they are autoimmune in nature, can result in neuropathy themselves, through antibody cross-reaction with nerve epitopes.

All I can say is that I really hope this thread helps some others out there that are suffering because I have to say my symptoms are subsiding big time and it must be down to the vitamin D levels.... if you read back through some of my posts I list my symptoms,they were getting pretty bad,not half as bad as some on here,and I really do feel for those people and what they have to endure,I just hope that this will help someone somewhere get to the root of their problem......

Greg,get all your vitamin levels checked..... they checked mine but obviously didn't bother with D,they only checked when I went to the doctors for something totally unrelated,it's well worth getting D levels checked...

People all vary in how they utilize nutrients. Drug use can also lower nutrients in the body (this is how many side effects manifest).

This new DNA test is almost here:

We are not all identical in how our bodies function.

Vitamin levels are sometimes misleading. They may show only what is in the serum and not what is being used
within the cells. The new Vitamin testing involves genetic flaws in vitamin use, and are not affected
by what you are taking. I think this new testing is very exciting, and may provide an increased quality of
life for many people plagued with vague and idiopathic or hard to diagnose conditions.

Most misleading are levels for some of the Bs and magnesium. Right now we don't have long term data on
the Vit D issue, but it is looking like we can trust those blood levels so far.

Thanks for the advice Mark and Glenntaj. I have been tested for several deficiencies, but not D. I'll get that knocked out in 2 weeks at my next visit.

Sounds promising Mrs.D. I've always been curious in regards to B12, how serum levels can be the ultimate gauge when it's not the "end of the line", so to speak, of the absoprtion and utilization process.

I have not read through much of anything in here yet, but have to say that I am hurting like I have not hurt in months...maybe 6? I have changed nothing and have only increased my decreased dilaudid intake. The last two days have resulted in a new 10 on the 1-10...all this in the face of great things going on personally AND with new hope of pain relief though topical mixes from San Ysidro Pharmacy in Santa Barbara, County. Need help. Need D info. Right hand is becoming useless at times (even doing this!?). Would easily trade some finger for a few days p/ mo relief.

Thanks and sorry for the gloom.
