question: 56 yr old female with recent onset intermittent, somewhat positional leg tremors in right thigh, and additional symptoms of chronic lumbar pain, focus of pain about two inches from the spine, sometimes radiating down the thigh (opposite thigh from tremors), and very mild vertigo. To complicate things, had injured right knee and had been treated with physical therapy and knee brace, which overlapped by about a week the beginning of the tremors ( I blamed the brace for nerve inflammation). Back pain sounds like sciatica, and is on opposite side from tremors, and and I was on a cruise recently, and blaming the vertigo on sea legs but I ve been on land 10 days already and still noticing it somewhat. Just bad coincidences, or something more major I should be looking into?
