If you mean the big ones on the back of your tongue it is normal, we all have them:)
really ive never noticed them they recently came up
those are actually large taste buds nothing to worry about 
enlarged taste buds or inflamed papulae. nothing to be worried about we all have them. yours do look a little bigger than normal. spicy foods in your diet can be a cause. dont worry! 
after taking a second look at your entire tongue. i noticed inflamed papuli all over your tongue. nothing to worry about but if the regular taste buds are inflamed like that. your larger taste buds on the back are not surprisingly larger as well. i think this has a lot to do with your diet as certain foods can do this to you. again not a cause of concern.
it’s what you’d call oral thrush. Its really hard to get rid of. some people have it for months. It’s a yeast infection in your mouth. You shouldnt eat dairy, gluten, sugary fruits, fried food, sugar, bread and a few more that i can’t think of right now. Oral thrush, since its on your tongue, feeds on what you eat. so all that stuff more or less makes it stronger
its not too hard to get rid of with medication. theres a few things you can find online as home remedies but you’d have to be really strict with yourself and your diet to really see results
it could be oral thrush. ask a doctor.
do you smoke and/or have a poor diet? it could cause taste buds to become inflammed.
