... Clinic in MN to try to find affected parathyroid gland this month but no success. One symptom I have that I have read on some limited websites that can be a symptom of unresolved hyperparathyroidism is neuropathy. My feet are numb and getting worse. I have spoken to a couple of endocrinologists but they seem to not be aware of this as a symptom. It really is a problem in my everyday life (I just turned 60, no history of serious health issues.) Anyone else heard of or experienced this symptom?
