You "bumps" could very well be concussions. The more concussions you have the easier it is to get another one. What symptoms do you have after these bumps?

Do you ever get a metallic taste in your mouth? That is a concussion. The dizziness or disorientation is also signs of a concussion.

When you bump your head, it is always a new event, even if it just appears to be a relapse of symptoms of a previous concussion.

If the previous symptoms come on without a head bump, that is called decompensation (relapse into old symptoms). If there is a new impact, then it is a new concussion.

I have had thirteen concussion over a 45 year span. I was unconscious only once. Now, I can get a concussion shaking my head NO. I get the metallic taste, disoriented, and foggy brain.

Some people get other sensations, strange smells, lack of sense of smell, sensitivity to common smells, ( coffee is a common smell that bothers some with PCS), ringing in the ears ( mine ring in the pitch of C6 sharp) , food tastes different or bland, visual abnormalities, and other sensations that are not like you have experienced in the past.

So, yes, you are having additional concussions. Stop doing that. Eventually, your brain will not have the ability to recover. The reserve capacity gets used up. Especially as you get older. Forty is the start of the down hill part of brain function. Recent studies say it starts at 27 years old, but after 40, it is very noticeable that you do not recover well.

I have found that Physiatrists and Rehabilitation Specialists are better at understanding concussions that the vast majority of neurologists.
