I'm certain that I'm getting slight vertigo symtoms several hours into an intermediate hike. The interesting thing is it's only hiking, mtn biking is never causing the same symtoms. The symtom is vision to the side moving slowly. I never get to the migrane headache and nausea stage of vertigo.
Curious if anyone has the same symtoms and what you do to treat it on the trail. The medical websites suggest Benadryl and Valium to treat.
Here is an interesting option:
Scopolamine is an oral, intravenous, ophthalmic or topical drug with many uses including the prevention of motion sickness. Transderm-Scop is scopolamine administered topically (through the skin or transdermal) via a special delivery system that gradually releases scopolamine onto the skin over a period of three days. The scopolamine is absorbed into the body through the skin. It is not clear how scopolamine prevents nausea and vomiting due to motion sickness. The vestibular part of the ear is very important for balance. When a person becomes disoriented due to motion, the vestibule sends a signal through nerves to the vomiting center in the brain, and vomiting occurs. Acetylcholine is a chemical that nerves use to transmit messages to each other. Scientists believe that scopolamine prevents communication between the nerves of the vestibule and the vomiting center in the brain by blocking the action of acetylcholine. Scopolamine also may work directly on the vomiting center. Scopolamine must be taken before the onset of motion sickness to be effective.
