Hi what is this on my tongue (7 months post chemo)

Hi what is this on my tongue please I was prescribed fluconozole 50mg for 7 days which is for thrush on my tongue ( didn’t work ) now using Daktarin which is a jel for my tongue to try help for oral thrush but not working either 😫 I went to the doctors and he was a training doctor and he said nothing was really wrong with my tongue but that day it didn’t look as but it’s not getting better I’ve been feeling really shit in myself no energy and a cough that I just can’t get rid of and I’m sure it’s down to what is on my tongue !? Ive had it for 2 weeks now 😢

My tongue also feels bumpy (back of tongue )

Please help what you think this is

I use to get oral thrush from chemo on my tongue but I’m still getting it now 7 months post chemotherapy I have dentist on the 9th January and I’m going to call the doctors again when they open back up on Tuesday

Sorry for the photos I have blurred them

Thanks
