Can 30% plaque in your carotid artery cause pain in the carotid/neck area?

Not a sign of plaque. 30% block in your carotid artery will not cause pain in your neck area.It is an indicator that it can compromise the blood flow to the brain if gets worse.One has to control the LDL levels in blood and bring it down with statins and diet.If it it prgresses to 60% or more, than you will need endarterectomy and reduce the chances of it leading to stroke.
No. Plaque in the arteries remain free of symptoms until significant impairment of blood flow after plaque ruptures and causes a clot or until the blockage becomes significant usually >80%.
