A mason aged 30 years came to me with the complaint of vertigo since a few days.. His vertigo was worse by lying in bed and turning sides, He had no other problem. I gave him conium 200, After four days he reported no relief. He told me that he could not lie down in bed and sleep, he had to sit down to avoid vertigo, so whole night he was sitting in the bed. On looking into the repertory, i found Lac Def. covering both the rubrics, vertigo turning sides in bed and also vertigo aggravated lying down in bed, must sit up, which cured him of his annoying trouble. He came specially to tell me about it.
In my practice, i used lac def for the first time in case of vertigo. Sometimes the key note symptom is so strong that we fail to take notice of the accompanying symptoms, moreover the patients also are not able to convey the problem with its modalities at first instance. It is only after our way of asking questions that they start focusing on their problem and are able to tell us in their subsequent visits.
