Sounds like this pig has a REALLY bad case of mange mites. The lump is probably an abscess he got from scratching himself. He is squealing because he is in terrible pain from the mites biting him. He needs medical attention IMMEDIATELY. If you or your parent is not willing to do this than he needs to go a shelter or rescue where they will care for him properly. Or he will die. Whereabouts do you live? we could point you to the nearest rescue.

Antibiotics are needed for the infection, and ivermectin is needed to care for the mites. Ivermectin can actually be purchased online or at local feed stores and administered at home, also, although I would not suggest doing so if you are clueless. Anyway, print out these pages and show them to your mom:
