No shakes from shooting Enbrel here: It does cause me to break out in cold sores around my mouth.I also got a swollen lymph node a week ago behind a cold sore on my chin in the below the mouth area.Sticking a needle in yourself is not a normal thing for humans.I take a mild trank called ativan or maybe a can of budweiser before I attempt to stick myself.My guess you are having a normal reaction to sticking yourself with a needle.Perhaps you need to calm down like I do with some minor depressant just before bedtime.i hope this is helpful.Needles are a drag but Embrel has recently provided much smaller less painful ones which i hardly feel.
