and while I won't specifically diagnose him I do suspect he is being treated for a number of contributing issues.

Did he trip on a rug or was there a clinical condition/ event that resulted in the fall????

i had to go to ER.

case by case when it comes to head injury

If you look at the pics of him with bruises, it's pretty characteristic of someone on blood thinners. A fall on blood thinners is no joke, especially if he suffered a concussion. Staying in the hospital for a concussion is rather unusual. If I had to bet, I'd say there's much more to this than we are aware.

a LOT of experience with similar cases.

Speculation only at this point*

Possible intracranial bleed, Subdural Hematoma might be something they are looking for. I doubt a epidural hematoma as that is a killer. Very fast buildup of blood in the brain. Subdurals are slow. Either way I think they are sitting on him in the hospital just to be on the safe side.
You our me? "Take two aspirin and call me if there are any problems"..

I think that's EXACTLY what's going on

Any fall and we had to take my husband to the ER. Some things didn’t even show up then. We discovered the bleeds later with the next fall. Falling with a blood thinner is dangerous and not to be taken lightly.

They will hold him as long as they feel there is a risk.

A curious question with even better answers.

We need more threads like this.

would be my guess

the blood thinner due to the concussion. Now they are assessing to determine when it will be safe to restart them.
Or
Testing to determine cause of fall. Stroke/Mini-stroke, heart issue etc

Why is this important? It sounds a lot like "Why is Fetterman still in the hospital?"

I don't care who it is, head injuries are nothing to mess around with.

I hope that he both recovers and retires. In fact, of all Americans, there are only two who's deaths I would celebrate.

He needs Super Doctor, Ronnie Jackson.
