Nothing icky, I promise. From a care conference this afternoon: Benign paroxysmal positional vertigo. It turns out that a blow to the head can dislodge crystals in the inner ear that can create this type of vertigo if the head is moved certain ways. Mom's physical therapist diagnosed that condition this morning and was optimistic that a few PT treatments would alleviate it. If that works it will be a huge improvement at this point, as mom is chafing at the orders to not move anywhere, even from wheelchair to bed, without an aide present. If those treatments work, she will be much freer to move around on her own and maybe even be home by next weekend.
The physical therapist was very confident, along the lines of, "seen it many times, fixed it many times." Cross your fingers.
