Normal ct, neuro did physical exam, thinks i don't have ms. i have tingles(buzz), hands/feet, stiff extremeties, ears pop, a lil lightheaded, tension in hea?

Not typical MS: Firstly MRI is imaging of choice for ms, not ct. Secondly, symptoms you describe are very non-specific. Head tension and popping ears are definitely atypical. If it's not ms, what does your neurologist think it is? If you don't get a satisfactory answer, get a second opinion.

What is the cause?: Those symptoms are common to many conditions, and they are not particularly strong evidence for MS. Tension in your head, could that be a tension headache? Tingling in the hands and feet. Is sensation to touch and temperature normal in those locations? How long have these symptoms occurred for?

Non-specific: symptoms-certainly not diagnostic of MS. This can be part and parcel of many mixed illnesses and do not suggest MS at all.
