Discolored places in throat

I noticed these painless yellowish places in the back of my throat about 5 weeks ago. At that time, my throat was a little sore from sinus drainage that soon cleared.

Now I feel fine, have no problem eating or swallowing anything, but these places are still there. I swabbed the places with a q-tip and nothing would wipe off and it was not painfull to touch. I have had a throat fungus before but I do not think that is what this is, I do not think they are ulcers either since I have no pain. The places have not changed color nor do I think they have changed in size since I noticed them and I have no other symptoms.

I had a lot of problems with throat infections and ulcers about 12 years ago before I had my tonsils removed. Do you think this is scar tissue that has been there for years and I just noticed it? Do you have any idea what these are?

Here are pictures I just took today all at the same time:

I brought up your pictures but they were not clear enough to make any type of diagnosis.You should either consult an ENT doctor or an oral surgeon for a definitive diagnosis.

I also added pictures from a few days ago.
