Is this scar tissue? Do I need a surgical procedure? (Photo)

I hope someone kind and honest can give me some advice and point me in the right direction,as this issue is depressing me. The people who put filler in my lips they filled it too much and caused trauma,I am no expert, but I feel it has stretched it so much it may of caused these splits in my top lip,which look like deep lines. Underneath the top lip on the inside i can still feel some lumps. I am told it might be scar tissue, what can i do about it without having to spend a few grand to fix?
