Erica Bloom, the main character in Cursed by Karol Ruth Silverstein, has chronic pain.
Karol says that Cursed is loosely drawn from her experiences following a juvenile rheumatoid arthritis diagnosis at age 13.
From the publisher:
14 year old Erica “Ricky” Bloom, is newly diagnosed with a painful chronic illness and pretty pissed off about it. Her body hurts constantly, her family’s a mess and the boy she’s crushing on seems completely clueless. The best coping mechanisms she can come up with are cursing and cutting school. But when her truancy is discovered she must struggle to catch up in school to avoid a far worse horror: repeating ninth grade.
