I have a 4mm pituitary adenoma, calcification of the pineal gland, a solid nodule on thyroid (biopsy next week), adrenal insufficiency, bouts of tachycardia, headache, blurred vision (opthamologist tomorrow), cramping in my extremites, mostly my right calf. Is there a common link that could be causing all of my symptons, and will I ever get a genuine diagnosis and be well again? I feel very poorly. All of my doctors think the headache is not related, as it started out as a coital headache on May 6, but has not gone away. Thank you
