Hello there. I need some sound guidance in my health situation. I am a female 50 years old. I have been a farmer, and worked hard all my life. I was always full of energy. Worked like 3 mules. Now I am at a dead halt. I hit a wall. I started to have double vision , severe headaches. I had 2 bad episodes of severe weakness, in which they lasted for a week. I live alone.I drove myself to the emergency center, and almost jumped the curb. They run a blood test, thyroid, urine, and it all checked normal. So i had a family doctor advise a brain scan with and without contrast. It reads on the findings. The anterior pituitary is enlarged to 9x9x9 mm and has a convex superior border that encroaches upon the optic chiasm as it bows into the suprasellar region. The impression states--- Hypertrophy of the anterior pituitary without discrete mass or differential enhancement. Recommend correlation for any endocrine dysfunction.Superior aspect of anterior pituitary shows a convex border that encroaches upon but does not definitively impinge the optic chiasm. Please let me know the best and what type of testing I need to get my life back on track. I am even having trouble concentrating and it is effecting my memory .... Thank-You also if you recommend a top notch endocrinologist in upstate South Carolina would also be helpful.

Hello, I think you need to get evaluated by a neurologist first. The cause of double vision needs to be confirmed. If you had weakness also, the thing whicChatDoctores to my mind is myasthenia graves. In this disease the muscles (including the one needed for moving eyes) become weak and so one starts having double vision. For evaluation tests like repetitive nerve stimulation test etc. are required which can be done under neurological supervision only. Good luck.
