handsomerube,

You have been told some bad information. Your doctor is not giving you the best information. Head bumps usually are NOT concussions.

Your somatic symptoms disorder comment has merit. Many who focus on every little event in life develop somatic symptoms.

When your GP diagnosed you with a concussion, twice, he likely was just using your subjective complaints and charting ICD S06.0 as a starting point in case you develop physiological symptoms.

None of your 'concussions' since 2016 sound like they were concussions. They sound like possibly sub-concussive impacts, at the worst.

Your posts sound like Concussion Anxiety Syndrome. You, like many others in the past decade, have been told that concussions are a serious risk and can lead to CTE and other devastating deterioration. You get startled by a head bump and that startle starts your mind racing. You notice sensations that you attribute to a concussion. More likely, those sensations are just anxiety.

A real concussion will manifest an immediate cluster of symptoms during the first seconds.

Many get startled by the bump can connect it to the dreaded 'concussion' and start LOOKING for symptoms. When you look for symptoms, you will find them. Do not trust those symptoms that you look for.

btw, Mayo Clinic online has been posting poor information about concussions for decades. Only 5 years ago, Mayo claimed you had to lose consciousness to get a concussion. They are slowly getting more accurate information but have a long way to go.
