Could you please correct it?
I heard that your son is sick and have an appendix pain. You had better to consult a good doctor otherwise it will be dangerous for your son. My brother had the appendix when he was just 14 year after the operation my brother become a strong boy. Before the operation he was a weak and thin and complaining pain in his stomach.
Here is a suggested version. However, if this is some kind of homework, please do not cut and paste my reply and use it as your own. I would like you to use it to get some ideas. I have marked in red each place in your original where there was a problem (spelling, punctuation, grammar etc).
I heard that your son is suffering with appendix pain. My advice is that you get your son to a good doctor as soon as possible as appendix problems can be very serious. My brother had an operation on his appendix when he was only 14 years old. Before the operation, he was weak and thin and constantly complained of stomach pains. After the operation, he became much stronger.
thank you very much for your assistance.![]()
