Many thanks in advance and sorry if any mistakes are done in this question
The question is how much do you believe to your doctor. If he was fine until now maybe you should continue to trust him and go for the surgery.
But since you are ready to ask for second opinion I don’t see anything bad in it. One more medical opinion can’t do any harm and it can help you to decide.
It has past some time since you have posted this question so now I would like to know what your decision in the end was. Did you get second opinion and what was the suggestion if you did? And which surgery did you choose in the end? And how is your friend now? Thank you for answering my questions.
