Geographical Tongue. Please help me!

Im having problem in tongue from more than a year. initially I thought its a geographical tongue and I used to scrap my tongue twice a day. First time when I consulted ENT doctor he told its a throat infection and gave some medicines. I have used for 45days but there is no luck. And again I consulted one more ENT doctor he said its due to vitamin deficiency and asked me to use Zincovit for 1 month. But there is no change. Recently I consulted famous dentist in my area, and using lyvit multivitamin and Methylprednisolone tablets from 2 weeks. and he recommended me never scrap the tongue. I have attached required pictures. Need suggestions to get out of this. My mouth is giving some bad smell because of this. Please help me
