Wow, Those hormone stimulating drugs are way off label. One is used for breast cancer, the other for infertility. I doubt many HRT specialists in the US would be willing to prescribe them for concussion. Off label prescribing would make insurance coverage difficult.

The online comments show them being prescribed by the sports performance focused doctors, often with steroids and such.

I'd stick with pursuing a neuro endocrinologist.

My symptoms were very similar to your son's. My mind was settled down with an SSRI. I eventually replaced the SSRI with 5-HTP and L-Theanine. The sensitivity to movements went away when my upper neck was treated and allowed to heal.

But, an important part of this is quite simple. Every head injury is different. Doing the various diagnostics to cover all the bases is worthwhile.

** Those drugs are commonly used for HRT for secondary hypogonadism where restart of the HPTA is the intent. They are not used if lifetime HRT is the intent.Google and you will see that.

Ok Ive done what I can here. **. Just want people to know there's a potential medically identifiable issue so they should get checked. The studies bear this out. If you are 20 and your testosterone is far below the range of normal then you have a medical issue. Giving them an SSRI does not correct that.
