I Was In A Vehicle Accident In 2015.Rearended,back And Neck

Question: I was in a vehicle accident in 2015.Rearended,back and neck pain but nothing broken.One bulged disc and spinal inflammation.Shortly after I began to have body function loss every few months and sometimes closer.
I was driving yesterday,and without warning I lost my body functions.I hit my brakes to stop my vehicle,but my body fell up against the steering wheel,my hands and arm became limp and I had no control to steer my vehicle.My held tilted sideways on the steering wheel,and I could see alright,but at an angle.After about 5 seconds after I stopped I told my wife she qwuld have to drive.I got out of the truck and went around the back to the passengers side,holding onto the side of the truck because I felt very weak.The weakness lasted for about two more hours before slowly subsiding.I do have vertigo periodically,but this is nothing like vertigo.I have no dizziness or spinning,just shutdown.Excellent health before the accident with the exception of vertigo periodically,which
I pretty much had under control by an herbal water pill I was taking.I'm concerned tha the back injury is causing the new problem.I have had xrays,catscans,MRI,with no positive results pointing to this problem.
