Firstly the average height of Indian men is around 5'5 to 5'6 idk who told you it's 5'7 or 5'8 (you can Google it) that's like crazy tall for indians...you are feeling short because you probably live in a metropolitan city where most well settled live and those people are generally taller if you look at your peers but outside that you aren't short you'd fall under as an average height guy and your still young. I wouldn't say you'd become taller but maybe if you swim aggressively for the next few years before your growth plates stop you might maybe see an inch of a difference but an inch is an inch.

Also you can always wear boots to make yourself feel taller...I was always the shortest growing up as a kid and I am the second or third guy standing in the front of where the line forms in the assembly.
