Oh boy...where to start?

First - welcome to this forum. You can find something about just about anything your daughter might experience on this journey. Use the search engine for info on specific issues. For example, I've never heard of blood pressure meds to treat PCS, but someone on here may have posted about it before so just type it in the search function. It actually makes a lot of sense to me. If not, start a new thread.

There are lots of parents of teenage girls here for some reason, and there are lots of teenage girls on here. There is something about the age/gender thing happening with head injury and post concussion syndrome. I am the mother of a 16 year old who is now 9 months post injury and still dealing with symptoms (lessening but still there).

I am definately not an expert, but rather than expending your time and money on a second neuro opinion, I would spend it looking for therapies. For example, does she need to see a chriopractor? Perhaps an endocronoligist to look at hormones? An ENT specialist to check for vestibular problems? A neuro opthamologist? Neurofeedback? Accupuncture? Neuros are, apparently, fairly notorious for the "rest and see" approach when there are some therapies that might help.

You are going to have to do the leg work and get it all figured out. Your daughter is still really early in her healing process. Some of her symptoms may not have even showed up yet. In my daughter's case, we had to wait for some of the constant symptoms to subside before she even realized she was having some vision problems.

You seem to have had the best advice for early treatment already (way better than I had) rest, rest, rest.

Others on this forum will provide you with better, more detailed guidelines. Just know that you are not alone, your daughter is not alone. This really sucks but you have come to a great place for support and guidance.
