Respected user, hi I evaluated your query thoroughly.
*Majority of cases are Idiopathic without any reason & non-significant in
absence of any other associated symptoms with it.
*Reason is transient hypercirculation of particular segmental vessel of the
body , in some instances blockage involving proximal / distal levels.
*Relax, relieve
stress , wait for sometime if its persistent / annoying then
consult a doctor otherwise it`s not an emergency dear.
Hope this clears your query.

you in the really needed time of
