Some people have some of these symptoms from the anesthesia from surgery, especially if they used Versed. It can take me a year to fully recover from Versed.

Have you ever checked your blood pressure when you have some of these symptoms ?

The subtle neck injury common to many concussions does not show in most imaging. It can sometimes be diagnosed by range of motion and crepitus but more commonly by being disciplined to sleep with good/straight head and neck posture and reaping the benefits. Some gentle traction and mobilization by a PT can help. For me, my neck was fine except when I slept. Then, it caused some serious struggles.

No have not checked my blood pressure. I do not have much neck trouble and Ann checked my ROM in my neck while i was there.
My concern is my symptoms seen to be getting worse. Not better

In my case, my only symptom of a neck issue was the struggles I had when I slept with poor posture. Stressful dreams, fatigue during the day, and some other symptoms that cleared up when I slept with good posture.
