camyam,

I can see how a generic endocrinologist would discount you. They know nothing about PCS or other head injury issues. Have you tried to find a hormone specialist who specializes in 'life extension' therapy? They often are more specific in their hormone analysis. The referral at https://www.womensinternational.com/..._referral.html is also good.

Did the physiatrist have any comments about your eye sight?

Do you have access to a therapeutic optometrist? There is an association for them. Maybe Eowyn or EsthersDoll will suggest the name.

What symptoms are you still struggling with?

Is you eye sight a functional limitation?
