A Time to Heal
Sam knew he was going to be in a world of pain as soon as his foot left the top of the basement steps. There had been no time to brace for the fall and no time to avoid it. He and Dean had been checking out a reported haunted house when the spirit they were searching for suddenly appeared behind his brother. He had no time to shout a warning to Dean so he did the only thing he could, he pushed his brother out of the way and in return found himself falling into the darkness below. He heard Dean shout to him and felt his brother try to reach out for him but it was too late, he was already feeling the open air beneath his foot and knew his fall into the basement wasn't going to end without some serious pain. He tried to relax his body the way their father had taught them hoping he could absorb the blow, but hope went out the window when he felt his lower back slam into the hard edge of a step. He actually saw stars as he lay crumbled in a heap at the bottom of the staircase. Upstairs he heard his brother cursing the spirit then heard the loud bang of the salt gun, the next thing he knew Dean was kneeling next to him.
"Sam you okay?" Dean asked as he put his hand on Sam's shoulder.
"Yeah." Sam said automatically, it was the response they always gave each other when asked it they were hurting, neither one wanting to show the other any sign of weakness.
"Let's get you out of here." Dean reached down to help Sam up, but all he felt at the end of his hand was dead weight. "What's the matter, you stuck on something?" Dean couldn't understand why Sam wasn't moving, he yanked even harder. He then felt Sam's hand on his arm.
"Dean…I ….I can't move my legs." Sam looked up at him and Dean could see the fear in his brother's eyes. "I can't feel my legs."
Later at the hospital
Sam had been taken back to the examination room while Dean paced the hallway. He had wanted to be in the room with his brother but the doctors hadn't allowed it, now all he could do was pace and worry. He hated being separated from Sam, he knew bad things always seemed to happen when they were apart, but he had no choice, the doctor had insisted. Finally two hours later one of the doctors walked out of the room and Dean immediately walked over to him.
"How's my brother?"
"Mr. Winston?" The doctor used the name that was on Sam's fake insurance card.
"You're Steve Winston's brother?"
"Yeah, how is he?" Dean was getting impatient.
"Your brother took quite a blow to his back, plus he has numerous other superficial injuries. What the hell happened to him?" The doctor asked as he studied Dean who also had bruises on his arms and face.
"I already told them at the desk, he fell down some steps."
"And what about your bruises?"
"I slipped going down the same steps……Now how is my brother?" Dean tried to control the anger in his voice; all he wanted to know was the condition of his brother not answer questions.
"Well the good news is your brother isn't paralyzed, but the bad news is he'll have to be off his feet and taking it easy for at least a week."
"What's wrong with him? Why can't he move his legs?"
"When your brother fell he hit his lower back and severely bruised it. The muscles around his spinal cord are swollen causing pressure to the cord which in turn temporarily paralyzed his legs."
"What can you do for him?"
"Nothing much except ice him down to reduce the swelling and then just sit back and wait for the swelling to go down. Once it does he should be fine, but he's in a lot of pain right now. I've prescribed a pain medication for him plus a blood thinner that he should take every four hours. It'll probably make him drowsy but that's to be expected. The main thing your brother needs to do is to rest and take it easy for awhile."
"You don't know my brother, that's easier said then done."
"Well it's very important for his recovery, if he further damages his back he might need surgery…. The good news is he doesn't have to stay in the hospital but he does need to take it easy and rest. … Do you live nearby?"
"No….we were just passing through."
"Then I guess we don't have a choice, he'll have to stay here for the week. There is no way that boy can be bouncing around in a car till he heals."
The brothers never liked staying in the same area once they were done with a hunt, they had always packed up and moved on but apparently that wasn't an option now…… But staying in a hospital always meant there was a chance they'd run into cops, and cops were something they always tried to avoid.
"We'll find a motel to stay at."
"That would be fine….There's a small motel out near junction thirteen, it's not a fancy place but it's clean and close enough to the hospital in case there are any complications."
"Complications?" Dean frowned; he didn't like the sound of that.
"Oh don't worry there shouldn't be any, but with any injury there's always the chance of blood clots." Seeing the worried look on Dean's face he added. "The odds of something like that happening are very slight, plus I've given him blood thinners so the chance of a clot forming is almost nonexistent. Your brother should be fine as long as he takes it easy and takes his medication. He just needs time to heal."
