sammietudor95, it sounds like a damaged disc. You won't know without a lumbar MRI.
Sadly, work likes to send us for an x-ray, so that the corporation never becomes responsible for medical costs of an on the job injury.
If it is a bulging disc, it could be pressing against the spinal cord. Bending forward creates more space behind the bulge and relieves the pressure.
Mine is a layman's guess, but you might want to request an MRI. The numbness after bending forward may indicate that the pressure could cause nerve damage. Sometimes bulging discs herniate initially or with repeated pressure, which causes me to suggest that you not wait. But sometimes bulging discs heal sufficiently on their own.
The insurance companies usually recommend PT as an initial conservative treatment. PT is often quite helpful, but best not until you have an MRI and know what is going on in your spine.
