Welcome to our forum Dsilva. There is a type of thrush that causes vertical lines, redness, and some pain. I get it often, but I am usually able to ignore it. Sometimes docs will prescribe an oral suspension that contains a numbing agent if it gets too bad. Docs are more concerned if you get a white coat on your tongue which is the typical thrush caused by yeast and is very painful.
How long have you had Lupus? I hope that you are feeling well. Feel free to post anytime. Love, Butterflake
