Ec sufferer

So i went today and MET different dermatologists, they discussed My condition and came to conclusion that i First DO a lip biopsy so they can make sure its EC and EXACTLY, but Also IF i have a intestinal disease. Afterwards she say Shes gonna put me on imuran and Will prescribe me a strong steroid cream thats usually prescribed by dentists to use for inflammation inside mouth.

Im really scared i'll get a big scar from the biopsy and that they Will find nothing. Any of you WHO did biopsy and was left with a scar/or not?

Also i maybe Will tell her to change the steroid cream to medium, DO you guys think strong steroid cream is too much ?
