I think i have endocrine problems but doctors wont check it out.?

I think i have endocrine problems but doctors wont check it out, the endocrinologist said my arm reflexes didnt work right and that meant signs of pituitary problems, but because the blood work came back normal i cant get any help for it, even though my joints are almost brittle too, my bone density was high risk but the bone scan came back normal, I get headaches a lot but cant get help from doctors like taking hormones for my joints, ive been taking stuff on my own like soy isoflavones for my joints and that seems to help. they have programs in my area to help financially but i think its like an HMO and if they dont feel like helping they dont. because stuff on tests dont come out, im forced to live without the help, any suggestions? I think pituitary problems run in my family, im also short about 4ft 5 and ive shrunk too, i was 4ft6, I gain weight really fast so i cant eat much, it takes me a long time to really feel hungry.not sure how to deal with all this.
