My 37 year old daughter had a stroke 5-27-2009. Her left carotid artery behind ear has large clot,no blood flow,so they say this is good. She was very fortunate that all that really is troubling her is her speech and thought process. My question is about pain in her neck past two days. She says it hurts on left side,not like a stiff neck but actually hurts.Is this something to be concerned about?
