Hi there,
Thanks for your query.
A pulsatile vein in the neck is suggestive of either, conditions which lead to increased blood circulation; a defect of the heart valve (called
Aortic valve incompetence).; or, an overactive Thyroid.
Causes of salt cravings include
dehydration (drinking less water),
electrolyte imbalance (due to lack of electrolytes, particularly
magnesium, in the meals)
constant mental stress/anxiety, underactive
Adrenal glands (located on the upper end of kidneys), or a kidney-defect leading to excessive discharge of sodium (salt consists of sodium + chloride) leading to sodium deficiency; or, a thyroid problem.
Consult your doctor and apprise him of my opinion. I am certain that he will agree with me, order required tests, and- based on the reports- will prescribe suitable/modified treatment as advised.
