Hi. So I ate this fruit called grape fruit which was unripe and a bit bitter. Last time also I had this throat pain for a week and blisters on my inner tongue and now suddenly since yesterday I have this pain in my throat which has become worse. I thought its sore throat. Now again on the inner side of tongue and on the base I feel that my taste buds are swelled up and there's a lot of pain. Any remedies for that? Pls help and advice.
