Laupala,

These minor bumps are of minimal significance. I think you are over thinking the risk from them. Your anxiety is likely causing your symptoms.

Minor head bumps only constitute another concussion if they have immediate symptoms, like blurred vision, mental confusion, strange taste sensations, dizziness, etc. It does not mean that minor head bumps are meaningless. They should be avoided. Many times, the concussed person has balance and other movement struggles that can lead to head bumps. It helps to learn to move more slowly and with purpose.

My best to you.
