Suggest Remedy For Dull Pressure On Neck, Face And Head

hi im a 25 year old male and ive had a sensation for the last year or 2 in my left side of my neck, face and head.its like a dull sensation or pressure that doesnt hurt or anything and it increases when i turn my head to the right. i work out all the time and use heavy weights. i think it could be a torn muscle in my trap area causing it. im so scared it could be something worse like in my carotid artery. any way ive always had by anxiety issues and ive even had a scan on my brain to make sure it isnt anything serious.i know i have anxiety but i can still feel this dull, pressure like feeling.any help???
