Question: Hello. Bumped top of my head (back left /side) yesterday agianst movable bus handle. Hard plastic. See attached pic. Still sore today. No other symptoms. At what point should i see doctor? Which symptoms? Abd how many days need to go by before i am in the clear regarding concussion or brain bleeding? I want to take an airplane flight within next week. Is that too risky after possible head injury, even without symptoms like nausea, dizziness, headache? Like i said, just soreness at the spot of contact. Is that normal for a minor bump? Please advise if i need medical attention or instead take wait and sse approach and for how long? And also, if can travel by plane a few days after bump.

Bus handle is a gray hook and appears at front right of picture.

My only symptom so far is soreness/tenderness at spot where head hit handle on bus. Top of head towards back left. I didn't lose consciousness or have any of the symptoms you mention. But can these symptoms appear afterwards? How many days/weeks do I need to wait in order to be sure I don't have something more serious? I am worried that symptoms might appear after I start my travel. Are the odds in my favour if I get by the first 72 hours without those serious symptoms, with diminishing likelihood they will appear days later? Or is it unpredictable - can brain bleed take many days or even weeks to manifest?

The hit seems minor, it was a bump really, but I read on Web how even minor bumps can lead to brain injury...is that an overreaction? So basically, are you saying I don't need to see doctor unless I get those symptoms you mention?

I understand brain bleed can manifest days or weeks later, but is it fair to say that odds of serious head injury dininish after 2-3 days of no symptoms?
