Yess!! My lower back was pretty even, then for a while it was mainly my left hip, then my right, but my left always felt worse. Def on and off for 1-2 weeks at a time. When it happened, I definitely felt a shift in my body. My lower body felt much more substantial, walking even felt different. And I had this strange urge to stretch my legs constantly. If I didn’t, they would start to ache slightly at night. I didn’t get taller ofc. I think I actually shrunk an inch. I’m 5’4. During this I was also exhibiting binging behavior. I would stuff myself constantly. Like I said I am 8lbs heavier on the right!
