Hi Hopeful
I have hypothyroydism too, and have had all kind of bloodtests to find the cause of my SFN. I even had a spinal tap. All negative. My TSH was up and down a bit last year. I did see a Endocrenologist. TSH and T3 T4 has been stable for a while. I will have it checked next month.
I do have inflamatory arthritis, so the rheumotologist think that is what has been causing the developement of SFN, even though it seems like the SFN was showing up first, and then the joint pains came.
I would like to see if the thyroid could be some of the cause.
I hope you find out all.

synnove, sounds like hashi's if your tsh up and down.

If you do blood tests, make them do T3 FREE and T4 FREE, they are more important that just T3 and T4. You might also do the TPO as high TPO indicates hashi's which means tons of inflamation, which is what I believe is my problem.

Staycy
I just checked on the script the doctor left with me to have blood drawn next month. The script says Comprehensive Thyroyd Profile, so I think this is included, I would have to check. I think it is T4, T3 Uptake Total T3, TSH.

I think perhaps I will see the Endocrenologist again, because my Hb AiC was up a little bit, and I have not been diagnosed with Diabetes.
But you know, it would not hurt.

You have diabetes, do you not?
Do you take diabetes meds?

Hope we all get rid of the SFN one day!!

No I do not have diabetes. I was pre-diabetic. I bought a monitor and I definately watch my carbs. If I don't , I would be well on my way to diabetes.

Hashi's/thyroid problems is connected with high cholestrol, diabetes, high blood pressure, arthiritis and so much more.

Hashi's I am learning causes a great deal of inflamation in the body, and inflamation can press on the nerves and cause PN.

Not all thyroid panels include the free's so I would ask for it, and the TPO if you want a real picture of the status of your thyroid.

From STTM site:

In most cases, Hashi’s is confirmed by two antibodies labs, and you need both, not just one:

anti-TPO
TgAb.

The first antibody, anti-TPO, attacks an enzyme normally found in your thyroid gland, called the Thyroid Peroxidase, which is important in the production of thyroid hormones. The second antibody, TgAb, attacks the key protein in the thyroid gland, the thyroglobulin, which is essential in the production of the T4 and T3 thyroid hormones. Note: it is unfortunately common for a doctor to only do ONE test, and you need BOTH tests, since you can be normal in one and high in another! Also, if your doctor just chooses the TPO, there are other autoimmune diseases that can cause a raise of the TPO. We have also noted that saliva does not always accurately detect Hashi’s as well as blood tests do.

I didn't get the TgAb, wish I did.

Stacy, I think I will have a visit with my Endocrenologist.
Thanks for all the information regarding the blood tests.

This thread is interesting!
 

Hi there. I have been following the thread and am interested that your doctors have attributed PN to hypothyroidism. Since getting PN after chemo I take 150mg of oroxin every Mon, Wed and Fri then 100 mg every other day. I take 100mcg of Selenium twice daily and upped my dose of vitamin D all thanks to my endocrinologist. I had my thyroid removed in 2004 and my current thyroid readings are the most normal they''ve ever been. My PN is improving with swelling reduced in my feet and toes. I see my endocronologist again in May for another review. Will definitely post again.
Cheers

You know aggie, I didn't really BELIEVE both doctors that hypothyroid was the cause of my pn. I just couldn't find enough to support it completely, so in my mind I felt maybe the fact that my blood sugar numbers were spiking so high (before my low carb diet) that the spikes caused my pn. Personally, going on my own, I decided to buy the meter and go low carb.

However, as time has gone on I have changed my opinion and do believe thyroid could have caused it. Before I got on thyroid meds, my heels hurt all the time and felt like a spike was in them, I had swelling all around my heels. Once I got on the meds that all went away and so did my PN symptoms, all of them. THEN after being on meds a bit the burning came back and has gotten worse and worse. Then it got better again when I increased thyroid meds, only to return a few weeks later.

While I wont ever really know the true cause, and it could be spikes in blood gluclose, or even my hydroclorothyiazide, I do believe it is the thyroid and now with hashi in the picture, that suggests inflamation even more.

Inflamation is a problem I already knew I had but I didn't know it was/could be from hashi's. And my burning improved instantly when I started with zyflamend for inflamation.

So, my new goal is to work on inflamation, bring my TPO antibodies down and see it that helps my burning/pn.

Just thought I would share my story with you in case it gives you any insight into your own situation. :)

Edit to add: I added selenium this week also, and I see you take it, so maybe that will help too. What kind do you take??? I have been confused on the many different kinds of selenium and some have yeast which is not good for candida.

Hi Stacey, I take Selemite B at the moment. It does have selenium and vitamin B of course and yes! you are right there is some yeast in it. I have to take selenium twice a day 100mcg each time so a total of 200mcg. Vitamin D also the same and of course I also take 600mcg of calcium. My heels were just like yours - so swollen that I stretched my sandshoes!! Thank goodness that swelling has gone. My toes are slowing getting normal feeling in them too. I still walk like a zombie but I don't care about speed anymore - staying upright and getting flexibility is top priority. I am being really cautious about sugar now too. I think I might have read one of your earlier threads about it aggravating PN symptoms so am trying to eat heaps more fruit instead. Also found that my feet really felt awful the day after a sugar binge. Eating my way through all those xmas goodies was literally quite painful. Next xmas its cherries, avocadoes, mangos and nuts for me. Hope you find the balance of meds and vitamins and send the pain packing!
