Thank you for your response. I haven't yet spoken with my doctor about the vertigo but plan to make an appointment. It was only triggered a couple other times and these were much earlier on (it's been almost 2 months since my injury)... so I assumed it was a "normal" part of early recovery. I wasn't aware there's a specific type of vestibular PT!
My one and only experience with a PT, with whom I was scheduled about three weeks after my concussion, was awful. The PT didn't do much of an evaluation, at least as far as I could tell. He had me do three quick visual tasks with small balls/beads on a string. These went fine and he announced we'd pretty much done the PT he specializes in. He then took me to a different room asked me to stand in front of a large screen and touch different sized and colored circles as they appeared and then as they moved within a larger circle that rotated in the opposite direction. This triggered an extreme episode of vertigo and nausea that knocked me out of work for two days.
I suspect (??) there was a scheduling error because this was my initial contact with this particular complete care center for head injuries. I called the PT to share what happened when I left after the half hour session. I played phone tag with the lead PT at the center, and also let my referring physician know what happened. I left messages asking for suggestions for follow up but didn't hear back from either provider. After last night's episode of vertigo I decided it's probably worth trying again to connect with a PT. I will inquire about Vestibular Therapy and am grateful you mentioned it. Thank you!!
I haven't really noticed any other recurrent symptoms, thankfully.
