I was helping my husband bleed the brakes on a dune buggy which was hosted up on a jack, the buggy jerked and fell of of the jack and hit the cement below. I was sitting the seat when the downward jolt occured, my stomach felt cramped and i felt achy all over after, but did not think much of it. today the aches are worse (ribs, shoulders, bad neck pain, and headaches) and my neck has felt warm to the touch since last night. Could it be reverse whiplash?
