Is a sick person rewarded for their pain, and is a father blamed for what his son has caused?

Firstly: A Muslim is rewarded for his patience and reliance upon Allah when afflicted with illness, whatever its type, due to the Prophet's (peace be upon him) saying: "No fatigue, nor disease...afflicts a Muslim, but Allah expiates with it some of his sins." The Prophet (peace be upon him) used to suffer from severe fever, and he informed that "No Muslim is afflicted with harm from illness...but Allah causes his sins to fall away as a tree sheds its leaves."

Secondly: There is no need to blame the father or sue the cupper; it is most likely that cupping has no effect on colitis or abdominal inflammation. Rather, cupping treats colitis and has no connection to what is inside the abdomen, as it relates to the outer skin, unless the person suffers from a hernia.
