I was on vacation a couple of weeks ago and didn't OP (I did buy some oil but had to chuck it - rancid - and never bothered to get more). I got back, full of toxic crud probably (all the trip food clogged me up, I bet). Anyway, I OP for a few days, then go to my massage therapist. Prior to going to this appointment, I thought the area under my chin was looking pretty puffy but not sore. My MT remarked how much stuff there was in that area & in my neck, rubbed in that region...and after the massage, I looked normal again. I bet OP prompted that - too much crap coming out too fast and spilling into that area, with my lymph needing a little help in handling it, perhaps?
