You've had this condition since you were a child. Unknown, with no cure.

A condition in which some part of your body would gradually start to hurt, whether you move it or not, to the point where it becomes unbearable.

John has already witnessed a few times.

Some that left you restless. Others that made you cry in pain. You even screamed in pain in some.

You were helping with the chores around the house, and sometimes you would gasp or hiss in pain.

That was the first sign of a possible 'vein attack', as you called. So John was already watching you, and prepared to help.

"Is everything okay? Are you in pain?" he asked as he approached, gently holding your hand.
