I was just rubbing the back of my neck near the centre and what I think was the muscle like clicked/slipped not sure how to describe it. But now I’m worried that I’ve burst my artery in my neck and I’ll have an aneurysm and stroke. Please can I have some advice, 20 y/o female.
relax u cant burst an artery by rubbing your neck. that click is called crepitus as a result of tissue moving around bones. i get that all the time. its not gonna hurt you. many people have this. 
Oh i get that often. Sounds/feels scary so can relate to your concerns. Still kicking though!
i have been through your situation at the beginning of this year but now i am free after along time all the doctors i visited around the states could not help me cus their medication was not working i finally get treated from a doctor abroad .So if your interested i can recommend you to him Anti-seizure medications may be used to treat seizures related to a ruptured aneurysm. These medications include levetiracetam (Keppra), phenytoin (Dilantin, Phenytek, others), valproic acid (Depakene) and others. those are the medication i took and i had to take them without prior prescription cus i needed to take some risk and it work for me well even though my insurance did not cover me but i tried paying for them by my self i am 26yrs
