Initially had episodes of sudden severe dizziness, heavy-headedness, and repeated vomiting. Muscle stiffness. Frequent lower back pain. Jaw clicking/crunching while moving. Difficulty walking steadily and maintaining balance. Poor concentration and focus ("brain fog"). Excessive daytime sleepiness. Low energy and low mood.
