However your tongue looks like there is thrush on it. I recommend a blood test also as well just to check everything is ok.
I had oral thrush and I never had just bumps on my tongue. I also had a yellowing coating on my tongue which got quite painful. If you go to the doctors and get a salvia test to check whether is then it could put your mind at rest and show whether you definitely have it or not.
if it is bacteria you need to take antibiotics for it, if not, then a full saliva and tongue test with blood test should be performed, I am not an expert in that , but i also had a white tongue, and doctor told me to do as i said to you.
Good luck my friend ( no alcohols, no spicy food till you are ok ).
Try Oil of Oregano, very effective in killing yeast!
