I am 25yrs old male. From past 2 yrs I am noticing that my capacity to eat spicy food is decreasing. In our family we always used to eat medium spicy food only but from past 2 yrs it has changed. I can no longer eat medium spicy food and its decreasing day by day. If I eat food that is spicy for me, I start getting hiccups and it only stops when my tongue is not feeling that spicy sensation. I am just confused what is happening to me.
