I had a weird, totally out of the blue accident early summer that resulted in a head injury, some brain bleeding and it temporarily affected my balance.
It's taken care and gone.Everything is healed....BUT
Scan is showing nothing, multiple scans actually, I still have a small persistent feeling of balance issue. It doesn’t actually happen, but i FEAR that it may. I NEVER had balance issues or fear of them in my entire life. EVER. I can't even remember ever falling other then playing hockey decades ago.
Brain surgeon chalked it up to my brain being psychologically defensive on its own. The feeling is better now the several weeks ago. It will disappear completely in time as the brain "forgets" the incident.
It's as simple as this, a physical trauma can induce psychological trauma.
Dach had serious knee injury and even though it's healed, he may want to do something physically but he has this fear buried deep inside his brain pulling him just a bit back. He is likely not aware of it as it's happening.
Dachs knees may be fine. Maybe perfect physycally, but not his mind.
Give him time.
EDIT....this is what my helmet looked like after my accident. I can't blame my brain for a bit of survival fear...nor Dachs brain for him being tentative to go into full bore contact.
Give him time...i don't know how long, but that trauma "should" wear off.
