Never had a vestibular assessment. I doubt I need my crystals reset. My understanding is this is needed when vertigo is presented. I've never experienced a spinning sensation. Only dizziness.
I realize potholes do not cause concussions. What I was trying to say is if you are in recovery mode it may trigger symptoms. This is called second impact syndrome. Could be very mild or fatal.
I'm currently in the midst of a relapse. Two falls within 2 weeks. Both falls landed me on my right hip and right arm. No head hits. No symptoms after first event. Right after second event I walked into a museum and after a few moments I felt mentally overwhelmed. I've had mild symptoms for the last 12 days, dizziness mostly.
I'm a regular biker and have stopped. The trail I bike is very bumpy and seems to make symptoms worse afterward. Normally it doesn't bother me.
So yes, I would say that potholes may trigger symptoms, did for me.
And since I assume most readers are recovering from head injuries I advise caution.
