Possibility: Usually term "buffalo hump" refers to a physical finding associated with too much cortisol. Cortisol is secreted by the adrenal gland, in response to a pituitary hormone called acth. Can also be produced by an abnormally functioning adrenal. Best to see an endocrinologist to sort it out.
