It is shown that steroids initially relieve symptoms of neurocysticerocis followed by worsening. House says that it is due to dead worms causing inflammation for which he gives albendazole (which is in fact used to kill the worm).

Gregory House suffers with chronic pain from his right leg and uses the walking stick in his right hand. In real life such a person would use the stick in the opposite hand (ie the left hand in his case), to offload the weight on the affected side and form a stable tripod base when mobilizing. This is basic knowledge for anyone in the medical profession. But, in later episodes of the show, it is made evident that House is using the cane on the incorrect side on purpose.
