I sustained a back injury when I began weight-training over a year ago. I was unable to bend forward; in fact, I would endure egregious amounts of pain unless I maintained an exaggerated upright posture. The pain disappeared completely after a few days of bed-rest. I believe the injury was caused by improper form during bent over rows. My form has gradually improved over the past year (though it's still horrendous), and I've been fine... until yesterday. I did not train yesterday - yet when I woke up from my daily nap I felt the same kind of pain I felt a year ago. A cannot so much as bend a few inches forward.
I anticipate that the pain will go away as it did before - but I'd like to know what is causing it - what kind of injury this is - and how I can prevent it. Any help will be appreciated!
(Oh, and, I will see a doctor... eventually).
