Thank you for telling the stories to us . It could have alerted some patients who experience similar problems to change doctors while it is still early.
After reading the sensitive case, I was sorry to hear about your father's case. That so called doctor smith is either neglience or incompetence.
Your father do experience discomfort and he should refer him to speciailists or at least do some test on him.
Anyhow, have you ever thought of breaking the matter to the attention of medical broad so that as to prevent this doctor from doing the same mistake. The law might have been on his side but at least , his name is black listed. Also , try to get your father's record from the doctor as soon as possible. He would have destryed it but may be, it is illegal for him to do so.
Personally, I also want to bring my case to the medical broad . I also got a stroke fifteen months ago because of severe hypertension thanks God that it is under control but I experience other problem and should have to change doctor again.
Well, I will pray for your family and God will with u. I under how your mother feel and it could have been painful for her to go thru all these. Well, may Our God comfort the broken heart , send blessings and peace to the family. May our Lord also give strength to help your mother go thru this critical moment.
