My first question for you will require some serious remembering.

Do you remember having any concussions or even just head bumps that left a bruise or bump prior to the last three years? You will likely need to spend a few days thinking about your concussion history prior to three years ago.

Second, tell us a little about yourself. Your post sounds like you are female. How about your age?

Have you endured any serious emotional stressors lately?

How about any prolonged illnesses or a high fever?

There are a lot of factors than can play a part in your situation. The above questions may help find some answers.

Your concussions and or head impacts may just be a cluster or may be related to your awareness of impacts to your head.

From now on, I suggest you keep a journal of any symptoms or further head impacts. Include the other things that are before your impacts, such as poor sleep, waking up feeling groggy, late night out, emotional stressors, chemical stressors (alcohol, medications, etc).

Hopefully, we will be able to point you in a direction for help or understanding.

My best to you.
