Is anyone suffering from bad back pain? I'm only 15w and lower back pain is horrible. I've even experienced muscle/skeletal aches all up my back amd my ribs... just once though. Do you think I could be carrying in my back? I have zero belly yet. Listeria is has been ruled out as the muscle soreness.

I should add my job is operating heavy machinery. I'm on the most gentle equipment (a watercart) but depending on the roads and dumps it's still rough.

Thoughts?
