My father suffered from stroke for a few years and was in a bedridden condition. We had consulted many hospitals but it was of no use. Later, one of my friends suggested me Chennai Brain and Spine Hospital.
My husband and I came to a relative's house at Chennai. We all were in a vacation trip. But unfortunately, during the journey, my husband fell down from the stairs of a famous shopping mall in Chennai.
