That is terrible. I sure hope that you have come through knowing clearly that your father was entirely at fault, and have found a way to put away that horrible trauma and find peace.
Definitely, fluid in the colon is a key element of preventing constipation. I don't know if a cyst on your left hip would come from the beatings, but bone damage could. Do you know for sure that what is on your hip *is* a cyst? Your doctor could certainly give you an informed opinion about your question.
I'm sorry this happened to you.
