My partner and I were called to an apt. for a male in his early 30's c/o severe head&neck pain.Pt denies any trauma,hbd,and curiously,has his hat pulled low on his head & refuses to take it off.His buddy,also hbd,is standing off to the side looking very nervous.vitals wnl,old abrasions and small lacs that've been treated are numerous.when questioned about these,he'd give evasive answers when a female cop entered the room,I tricked him into removing his hat and found 4 smalll,round wounds at equal distances around his head with slight bleeding.Again,he became evasive till my partner lifted a blanket in the corner covering his HALO !! He finally came clean & admitted he'd just been discharged from the trauma center after an mva he broke his neck in.He said he couldn't stand to wear it anymore and talked his drinkin buddy into taking it off! While informing him of how stupid this was,we carefully c-spined him and transported him back to the same facility.The same trauma surgeon was on duty and waiting for us at the ambulance bay.LET THE ATTITUDE ADJUSTING BEGIN!!!! The doc informed him that if he thought he was uncomfortable before,he ain't seen nothin yet.We were cringing and we weren't even the ones getting chewed out.HERE'S YOUR SIGN!!!
