I have emphasized Mars in 4th house. In a night chart.
It means rather unpleasant things = being subjected to anger and aggression/passive aggression in childhood in various forms, two heavy life-threatening bacterial infections, other people commonly misinterpreting me as bad tempered/aggressive/agitated/in a great hurry etc. [ while my bodily movements are just faster than average]. Just to name a few.
I won`t list more, as my posts are sometimes misinterpreted and, consequently, removed.
All the above have certain unpleasant consequences that will never even fade, not to mention going away, I`m afraid.
Scars? eight on my face alone, but only one of them is (barely) visible, so anti-esthetic effects are none. They`re result of surgical removal of moles. Nothing serious or damaging. I had lots of moles all over my upper body, but they`re mostly removed without much scarring. I had a tatto on my arm, which is partly removed, this scar quite visible in terms of tissue quality, not color.
Pain? I know the worst physical pain that can be experienced. Even medical doctors admit that there can be nothing worse than that. This pain, however, is nothing compared to emotional pain I experienced in my life. The emotional one is chronic.
The only positive about this Mars is my inherited talent and love for sports. I don`t like watching it, I love doing it because of heavy beta- endorphin release I experience. In fact, sport is the only constructive activity I feel I can be good at. And used to be one of the best in my school. Heavy training soothes pain for a few hours.
All the rest is moderately to very negative, depending on transits to my natal chart.
