i also have this prablem, im now taking 5,000 units a night.

I was showing alot of fatigue and I told my doctor that I thought I needed B12 shots and she tested me and sure enough It was low and I started getting a B12 shot and that gave me a quick boost. So it did help me with the fatigue it was not a miracle cure.

I think alot of times doctors have to take so many blood test because maybe and I am not sure but that the individual body might take in certain meds different and there is not set amount to give. It is all a bit of an experiment. I think another doctor might have to do the same things so I would not invest in any time looking for one unless there were other things your doctor was doing that you did not like.

Hopefully it will level out and all the test will stop to back to just annually.

Interesting.
I had complete bloods done when I went to my new doctor and he found my D was low and I was tired and no energy. He put me on 1,000IU a day and my energy increased and that horrid tiredness went away. I will get him to do another complete screen in a couple of months to see what my levels are on that and other things including liver and kidneys. When I start getting flat again I up the dose to double for a few days ans then drop it back. I have also tried to get more sun but there is none at the moment here.
I did read that your body regulates the vitamin D but if you can't/don't get enough (15 minutes full body - have fun with that one LOL) then you do need to take a good quality D to keep the balance right. But 500,000? That is a very high dose. I think I would be climbing the walls with that much.
I agree with some others, I would find another doctor (if you can) as this one does not give me much confidence that she knows what she is doing.

Wow! These posts are eye-opening. Having read about the inclusion of vitamin 'D' as part of the daily regime, and after being diagnosed with osteopenia, I was told to take the supplement everyday, although a specific dosage had not been recommended. I was unaware that it could be toxic to the liver taking it large doses. Also I've never been tested so I don't know my level. I wonder why this test isn't part of the routine when blood work is done. I know now to start looking into getting my levels tested. Thanks to all of you for your posts and for sharing so much information.

So...just saw my doc. I'm going to be changing pain meds when my insurance gets done fighting with me. I'm also trying another pain clinic, though the last one told me to take Lyrica!

I asked my doc why my script was for D2 when I read that D3 is more easily absorbed. She assumed that's what they were giving me all along!

I agree that it is the new diagnosis catch all. Mine was 7, and I was put on 50000 units weekly. Never have been retested. Never thought it was worth taking. I am constantly in the sun. Have the dark tan to prove it. To top it off, though it was a prescription, the insurance would not pay for it, as they considered it a vitamin.

I have D, B12 and fish oil all covered by insurance. Having your level checked again might be a good idea. If it's too low, it can damage your bones! Mine has been up and down. Hopefully I'm on a therapeutic maintenance dose, now.

I used to have a problem of low vitamin D levels no matter what - until I lowered my intake of vitamin A to a healthy level. My mood did in fact improve. (Pain - probably not. I think the type of pain matters.) There are other substances that can interfere with vitamin D levels.

Stomach problems can, too.
Also, the over-the-counter form should be Vitamin D3. D2 isn't absorbed well.

It's interesting that you mentioned the difference between D2 and D3. I recently asked my doctor why she chose D2 for my script after I'd read about the differences. She was baffled because she assumed the pharmacy was giving me D3! She just wrote me a new script for 2,000 units of D3...specifically!

The only other supplements I take are B12 and fish oil...when I remember.

I was also the record-setter in the clinic I go to: it would depend on WHAT your levels are, as whether you need to move on; but I too, am getting the mega doses. I just checked the symptoms of Vitamin D toxicity ( anorexia, diarrhea, constipation, nausea and vomiting. Bone pain, drowsiness, continuous headache, irregular heart beat, loss of appetite, muscle and joint pain are some other early symptoms that are likely to appear within few days or weeks after you've been consuming too much Vitamin D); and have been watching out for them.

But my D-2 levels were zero...undetectable; on the lab slip. The D-3 levels were slightly better at 7, and she had them check it twice, dragged me in for a repeat draw, with the exact same results. So, since this recent discovery; I've been prescribed 50,000IU of Vitamin D-2; and then will be on 800IU of Vitamin D-3 for 8 weeks, followed by monthly rechecks.

I'd hoped also that there'd be some improvement in symptoms, but as with vitamin deficencies, it takes a lot of time to build up a steady blood level, I've noticed nothing yet either :-(.

But also, the barometer has been making life miserable, but I have 2 awesome boys to cheer me up; only right now-I had to break down and ask my brother to help me out for a few days and watch them; the flare is kicking me senseless!!! ~:0)

I never imagined hearing from so many with the same problem when I posted this topic! Be sure to have it monitored closely as mine went from 6 to 68 in 5 weeks!

I'm glad you have a wonderful brother to help out!

Wow, good to know!!! Was that your D-2 or D-3? My D-2 was undetectable, and my D-3 was 7 which of course makes the total 7, so you mighta even beat me!!! My good friend in Houston has the same problem and even her numbers were higher, and she was the record-setter at her docs: Her D-2 was 6 and D-3 was 7, and THAT was the lowest her doc had seen!!!

So, maybe we can do what everyone does and blame it on global warming???

I wonder if there is a connection between low vitamin D and CP..... and if so which comes first?

One thing I do know is that once I started taking it I did get more energy back and felt a lot better. When I get my next full blood screen done I will get my Dr to add it to the list. At the moment he is concentrated on the A-fib and INR (clotting factor) test.

You know, it might be a connection between Vitamin D defficiency and chronic pain, maybe the NIH will do a study one of these days...... You know, when I go see my GP, I am going to ask him about this, he does a lot of research in our local hospital, and I am sure that this will maybe put a grain of interest in his brain, we'll see.

I believe I recall reading an article in one of my journals (from my RN days) that there has been discovered a LINK to low Vitamin D levels and CP: but they are still trying to figure out which came first.

My opinion is it's gonna end up being the chicken vs. the egg question...JIMO....
