This answer was rated:

for the past week i have been feeling extremely dizzy and lightheaded, when i walk and when i lie down and i have also been feeling very nauseous (without vomiting). I have had a fuzzy feeling in my head and it feels like i can feel my pulse throughout my entire body. This has been accompanied by headaches and fatigue and a loss of appetite. but i havent had any ear infections or bugs recently, it came on suddenly.
Hello from JustAnswer.
It will help if you could provide some further information.
Does the lightheadedness get worse when you move from a lying to a standing position?
Are you able to check your blood pressure and pulse at home?

It doesnt get worse when i move from lying down to standing, however it does get worse when i start to walk and unfortuneately im not able to check my blood pressure or pulse at home

Thank you for the additional information.

The most common cause of the symptoms that you describe would be from inflammation of the inner ear, which is most often due to a viral infection, even if not causing other symptoms that are suggestive of an infection.

Dizziness and lightheadedness also can be due to dehydration, but the symptoms would usually get worse when standing from a lying position.

It is possible that the symptoms could be related to a low blood pressure or excessively slow or rapid heart rate, although this is very uncommon in an 18 year old.

There are some over the counter medicines that may help ease these symptoms, such as meclizine or dimenhydrinate. It also would be reasonable to be drinking plenty of fluids, even if there is no worsening of symptoms when standing. If the over the counter interventions are not adequate, then it would be reasonable to be seen by your doctor.

If I can provide any further information, please let me know.
