Yeah. My weight goes up & down a bit. I'm 6'1" and about 185 now, probably 12% fat currently. Been as heavy as 215 and low as 175 in the past 4 years. And some mild up & down in between, but a steady decline generally. When my diet is cleaner, or my body composition is improving and I am dropping a lb a week or so, my torso where I store my fat kind of hurts. Like not pain, but discomfort; sort of a slight burn and a bit like DOMS. I've never heard of this and since I am in this clean up phase and experiencing the feeling, thought I'd post.
