All hernias are considered injuries within the provisions of this chapter causing incapacitating conditions or permanent disability, and until otherwise ordered by the commission, the following rules for rating hernias shall govern:
If the facts in subdivisions (a), (b), (c) and (d) of this paragraph are proven, the hernias are considered to be aggravations of previous ailments or diseases, and will be compensated as such for time lost only to a limited extent, depending upon the nature of the proof submitted and the result of the local medical examination, but for not to exceed two months. Hernias of every kind shall be compensated pursuant to this paragraph unless the claimant proves to the satisfaction of the commission by a preponderance of the evidence that the hernia is a real traumatic hernia as defined in paragraph 1.
