m standing on an airplane, even when sitting down or lying, I feel as if the floor and the
world around me is shaking like an earthquake. My ears have wax, but I don't think these cause the balance problem. 7 days ago, I took an airplane, but jetlag shouldn't last this long (if this is jetlag, that is). The night before boarding the plane, my right arm had a numb feeling, sort of like after an injection to the muscles, which consisted of the feeling of dull, numb pain.
