Need few more details to figure out the exact problem.
Is it present only in the morning?
Does it happen every time you turn your head or turn around in bed?
Does it happen when you suddenly stand from a sitting or squatting position?
Next Steps
if it is while turning your head or changing position then you need to see an ENT surgeon.
if its mainly when getting up try rising slowly, check your BP, ensure good fluid intake.
If you feel heart is beating faster or that you feel hot all the time or are sweating more than usual do a
thyroid function test and see your physician
