Draco wasn't sure how he'd gotten Dragon Pox but he was doing his best to figure it out from his sick bed. It wasn't as if he had a great deal of contact with the outside world which was probably the easiest way of catching the disease which meant it was probably something brought into his house from one of the elves, either on accident or purposefully to harm him. At first he'd nearly fired the elves on the spot but luckily before he did he realized they were far too loyal to do something like that on purpose and besides that, if he did get rid of them, he would be absolutely helpless and unable to take care of himself. Reluctantly, he'd decided to let them stay, at least until he was on his feet and could investigate himself.
If they hadn't done it on purpose meant, naturally, that someone had given them something for him that carried the disease on it. His list of enemies was longer than he knew but the items he'd come in contact with weren't and once he'd tracked them all down he had his doctor take them away to be tested so he could get to the bottom of who was trying to kill him.
While suffered in wait, confined to his best by his doctor's orders, not that he would have much strength to get out and do anything if left to his own devices. Being sick was miserable, the Dragon Pox was worse. His pale skin was covered in angry green spots that itched and hurt when he touched them with anything, even the clothes against his body. It meant he was in a constant state of pain. It made sleeping, eating, drinking, breathing, anything miserable and at times impossible. He was exhausted and cranky, sure he was going to die, and there was nothing he could do about it.
His day, like most of his days, was spent trying to sleep while not moving. He'd long ago shed his clothes, sent them away to be destroyed, and lay as gingerly as he could between silk sheets. Next to him was a bottle of lotion his doctor had given him to put on spots that became unbearable as well as some pain killers and a sleeping potion.
Possibly the worst part of it was he was alone. He couldn't tell his mother, she would lose it and, even worse, probably want to come over. He definitely didn't need to deal with her, probably drunk and trying to mother him. She'd definitely just make it worse.
