Neurology? Endocrinology? Cardio?

Ive been going to doctors with this since i was 15, and every now and then another symptom is added.
It started with exercise intolerance when i was 15- mostly aerobic. While i was really good at un-aerobic exercise, running made me short of breath, my head and ears felt really hot, pounding and it took me about 2-5 minutes of lying to be able to function again.
Somewhere in the following 12 years, intolerance of heat and excessive sweating was added. Overall fatigue, and sleepiness throughout the day- including while driving.
Tremble of hands was increased in the last year, to a point where people constantly asking me about it.
Blood work completely  normal- was never anemic, no iron,vit b,b12,d deficiency's, tsh levels are always normal, liver and kidneys functioning properly, blood count is within limits. Negative for lupus and lime disease, up to date with all my vaccinations. Theres just a slow worsening, never had a remission episode or something.
Resting heart rate since 16 y/o is 100, no arrhythmia, bp is normal, saturation is normal. Taking beta-blockers for the hr- brings me down to 80-90 resting heart rate.

im tired of hearing doctors ask me if i function properly on a daily basis and saying "well, this symptoms is weird but you are fine", i want to treat this somehow BEFORE i stop being able to function..
Any idea would help!

I know you said your TSH was “normal”, but I’d really like to know what the actual reading was.  I’d also wonder if TSH was the only thyroid related hormone that was tested.  TSH is a pituitary hormone,  not an actual thyroid hormone, so it shouldn’t be used alone to determine whether or not one has a thyroid condition.  

That said - you need, also to have Free T4 and Free T3 tested, which are the actual thyroid hormones, with Free T3 being the one actually used by individual cells throughout the body.    Even if these hormones are “in range”, they can still be too high/too low for you.  In your case, I’d say they’re too high because all you  symptoms are those of hyperthyroidism.

You also need to have thyroid antibodies tested, as both, Graves Disease and Hashimoto’s can be associated with hyperthyroidism.  Graves Disease is always associated with hyperthyroidism.  Although Hashimoto’s is, typically associated with hypothyroidism (low thyroid), early stages can be marked by periods of hyper, alternating with normal and/or hypo.  It, ultimately, ends with hypo.  

The antibody tests you need are Thyroid Stimulating Immunoglobin (TSI) to test for Graves.  Thyroid Peroxidase Antibodies (TPOab) and Thyroglobulin Antibodies (TGAb) will confirm Hashimoto’s.  You should also have a thyroid ultrasound to determine if you have nodules, which can produce thyroid hormones independently of the thyroid.  

I’d also like to know the result(s) and reference ranges for the Vitamin B-12, D, and iron.  Vitamin B-12 is one that needs to be at/near the top of its range in order to alleviate symptoms.  In addition, B-12, D and iron are necessary for proper utilization of thyroid hormones.  

Any type of doctor can order these tests for you and if your current doctor refuses, you should find a doctor who is willing to do them and rule out a thyroid condition.

And yes, unfortunately my doctor refused, am looking for another gp..  
I can tell by looking at them that your B-12 and Vitamin D are too low.  Even though your B-12 is "in range", it needs to be close to the top of its range in order to eliminate symptoms.   Although the lower range for Vitamin D is around 20, levels actually need to be around 50-60.   Vegetarians or vegans are often low/deficient in B-12, which comes primarily from animal sources, such as meat, eggs, dairy.   Elderly and those who spend all their time inside are likely to be deficient in vitamin D, which is actually a hormone the body makes from the sun.

I'd suggest that you begin supplementing with, both, B-12 and D.  For B-12 make sure you get a methyl B-12, which is more easily absorbed.  

I'd have to see the reference ranges for the other parameters as the vary lab to lab.   Although your Folic Acid (Folate?) may be in range, but on the low side.  B-12 and Folate work together.  

Your TSH is on the higher side of normal and you really need Free T4 and Free T3 to be tested.   As I noted previously, Free T4 and Free T3 are the actual hormones produced by the thyroid, whereas TSH is a hormone produced by the pituitary gland.   High or low TSH does not cause symptoms - symptoms are caused by the levels of the actual thyroid hormones.   It's unfortunate that too many doctors are set on testing only TSH.  

I'm sorry your doctor refused to do additional testing, but since s/he did, I agree that you need to find a different doctor.
