Purple lump in my lip. What should I do? (Photo)

i had my lips done months ago by a bad practitioner and i got a full refund of my money for both times i had been which in itself is weird because you wouldn’t refund someone if you’d done nothing wrong, anyway i’ve had this bump since the first time i had it done i’d say about 3 months now and i accidentally have bitten it last night and it’s a purple colour now and won’t go away what should i do
