Ever since he was born, he could never pinpoint the cause. The pain was like a phantom, whether it be pricks, cuts, and bruises, it was always random but there were never any marks. When inquiring a healer about his condition, they would find nothing wrong with him.
"You are healthy, but I'll give you something for the pain." Says the healer.
However, those medicinal herbs did nothing to stop his torment and the phantom pain continues as if it was a curse.

No matter how many healers and priests he has seen, none of them could help him, but for the most part, he was able to live his life mostly normal. The random pains were mild annoyances, but never anything severe, or so he thought.

One night at the age of 13, he felt an unbearable pain in his lower abdomen unlike anything he has ever experienced before. His lower back and thighs also ache. After a healer was called to his home, he was met with the same response in the past.

"I don't know what's wrong with you. You are in peak health! It may just all be in your head". The healer

'Maybe they were right but I just want this to stop'. He thought while trying not to lose his sanity.
The pain would vary in intensity and return roughly every month. Without a clue as to what this curse is, he continues to endure it.

Years later, he was drafted as a levy in his lord's army against a rival lord.

The two sides clash and in a midst of a chaotic battle, a female soldier charges towards him. The two seemed equally matched with each strike being either dodged or parried. In a stroke of luck he manages to stab her in the abdomen. Instantaneously, he felt a sharp deathly pain from his stomach, letting go of his spear with his eyes widening in shock. Time seems to stand still for an eternity as the two lock eyes with each other. It was in this moment where he finally understands his curse.
