Low end of reference range TSH, FT3 & FT4
Not sure I can do this or not....but are extreme hypothyroid symptoms that continue to get worse plus eye blurriness, light headiness and weak arms and these lab ranges be indicative of Secondary Hypothyroidism? Just desperate to find answers :(
levels (Verified Reference Range )
TSH .596 ( .465 - 4.680 uIU/mL )
FT3 3.02 ( 2.77 - 5.27 pg/ml )
FT4 0.86 ( 0.78 - 2.19 ug/dl )
Ferritin 11.3 (6.2 - 137.0 ng/ml )
Vitamin D = 53 ( 30-100 ng/mL )
B12 391 ( 239 - 931 pg/ml )
This discussion is related to Thyroid or Pituitary.

Cymbalta does all kinds of weird things and it acts a lot quicker than levo does.
I am not sure why I feel good this morning....could have been a virus I am overcoming or the vitamins are taking a hold...been on the B12 a month now...I still am pretty weak and fatigued. But I do feel different today....I don't think its placebo...I think either I had a small bug, low vitamins and thyroid issues or all three going on and I felt worse with two or all of everything. Nonetheless...I feel a bit better today & I think I can only go up from here...not sure about the Levo...two pharmacists tell me if you are low enough that the Levo can help right away....don't know I guess I am not a pharmacist or a doctor. But I still am pursing answers....all I know is I felt terrible the last 2-3 weeks and the thyroid symptoms have been going on a long time...
My TSH has been below normal for 4 yrs now but no one ever checked my T3 & T4s so I don't know how long they have been low. This started in 2011 and I have been diagnosed with Firbromyalgia, Depression, Anxiety, weakened immune system...the Body is tough because everyone is different and their bodies all do very different things and it takes so much to keep it all balanced and I am finding if one thing is outta waco there can be a domino effect or really make a person feel out of sorts.
The one thing that has become a new symptoms in the last two days is my weak arms....the get really weak feeling right like the feeling you after you life weights or plank a long time....they slightly quiver but feel weak where I can't do to much with them. Its faint not drastic....wonder if its a Cymbalta side effect? I had it before I started the Levo....Know much about Cymbalta? I just started that Monday this week.

True it takes me 3-4 weeks to notice even the tiniest of changes when I change dosages.
But everyone is different.

Not sure why you'd feel really good after only one dose of levo - probably a placebo effect, since it does take 4-6 weeks for the med to take full effect, though some do feel slight effect after 2-3 weeks.
Pituitary issues only affect the pituitary gland, which is in the brain, and the glands it controls; it doesn't affect other parts of the brain. Hypopituitarism can cause issues with just one of the endocrine glands or multiple glands. Eventually, if the thyroid med doesn't alleviate your symptoms, you'll have to test other hormones, but I'd give the thyroid med time to work. That's just me, though, as I prefer to rule out one thing at a time.
It's always appropriate to know if we have an autoimmune issue, because if we have one autoimmune disease the chances of getting another become greater.
I have Hashimoto's (autoimmune), which is the most common cause of hypothyroidism. I also have Pernicious Anemia, which is also autoimmune.

I feel really good today and it was the first dose of Levo...I am assuming it will look up from here. But I am still concerned with pituitary issues...with them being on the low end...it doesn't seem very common from what I have read in research and if it may have something to do with any part of my brain...I would like to know.
I think asking him would be appropriate at this time and especially autoimmune. I am not sure why he would check me soo soon either ....I will ask him tomorrow his reasons for checking at 2 weeks....thanks for all your help. Barb...do you have Hasi's or Central Hypo?

If you've just started on the levothyroxine, you'll have to give it time to take effect. Testing after only 2 weeks is pointless, since it takes 4-6 weeks for the med to reach full potential in your blood.
I guess I'm not sure the point in pituitary and adrenal testing, right now, but if your doctor agrees to do the tests, you might as well. I agree with testing thyroid antibodies to confirm/rule out Hashimoto's.
I understand that you feel bad, but it does take time for the medication, as well as the vitamins/minerals to bring all your levels up to where they should be and there's not really a lot you can do, but wait for the med and vitamins to take effect.

Yes...this post was an accident! Sorry about that....I got a call from my doctors office today...starting me on Levothyroxine .05 mg and 325 mg of Iron and continue 1000 btus B12 supplement. I am also adding some Vitamin D on my own.
The doctor wants to see how I do on the Levothyroxine and check levels again in two weeks. I kind of got really hyped up and wanted to see the endocrinologist right away but I am willing to try this as I trust this doctor.
Also I made an appt. in two days and am going in to see him and insist on running some pituitary, adrenal and autoimmune tests and see if he wants to do a scan at all. I am just feeling the worse I have ever felt and the symptoms seem to hit me HARD the past 2-3 weeks....now I am fogged out mentally and can not even concentrate on my studies and I feel like I have the flu...sore and achy all over and in my joints...tired. I can't live like this anymore :(

I just realized that lilminniegurl has another thread going with the same information. We probably don't need to keep this one going, as having multiple threads with duplicate information only adds to confusion.

In addition to the vitamins which Barb135 mentions. Which I agree with completely.
Many people do not feel normal if they are symptomatic until they have BOTH of the following as a target.
1) Free T4 to be 50% of the range or slightly higher. Your testing at only a pretty dismal 5.7% of the range. A FAR cry from 50%
and- means in addition to
2) Free T3 to be in the upper half to upper 1/3 of the range. (50% to 67%) Your testing at only 10% of the range. Again a far cry from above 50% and most need closer to the 67% to feel well.
Understanding that every person is an individual and feel well at different blood levels. But at least the targets being much higher in the range seems to be where people feel better.
Being "somewhere" in the range is simply NOT good enough for most people.

Are you on a thyroid replacement hormone? If so, which one, what dosage and for how long have you been on it?
If not, then yes, your results, could indicate central hypothyroidism.
Your Ferritin is way too low. You should ask for a complete iron panel.
Your B-12 is also too low in the range. You should try supplementing to bring it up close to the top of the range. Levels that are too low in the range can cause symptoms of fatigue, numbness and tingling in the extremities, easy bruising, brain fog, difficulty concentrating, etc.
Your vitamin D is not "horrible", but you should try supplementing to get levels closer to the 60-70 range.
Low levels of B-12, D and ferritin can cause hypo-like symptoms.
