I gonna leave ... Is that true?

Yesterday, I went to Saint Paul hospital to check how my backbone is going on after 12 years of operation. On Tuesday, an old doctor there gave me an appointment from 14:00 to 16:00 on Thursday to have the consultation held by many related specialists in this field. My sister and I came to the hospital right at 13:50 and after going around, we were instructed to go to the right place to meet right persons. There, one of them said that we should wait until 16:00 'cause it would be the time they hold the consultation.

Although I got a cold before and felt not very well then, we must be patient more to wait ... sitting on a chair under the blue sky ...

Finally, it's time for us to go up stair but still have to wait a little more to be called ... More than 16:00, a doctor told me to go inside.... They invited me to sit down..

D (Bone Dept Manager): Why do you want to check your health this time?
N (Nightingale): Yes, I wanna check my backbone regularly after the surgery 12 years ago, and because my right leg become weaker and weaker ...
D: Come here ... standing in front of me and turn your back on me.
...
(When the doctor finished watching my backbone, I just stood there and answer their questions. Suddenly I heard another cold and hard voice behind me: "Sit down, ok? That's your seat!")
D: Ok, by seeing the X-ray image, I advise you to have one another surgery to remove the steel frame ... The reason is that after 12 years, my backbone has become steady and now the frame turns to be redundant.
N: Will that operation be dangerous for my health?
D: Why do you think its dangerous?
N: I don't know ... (much about health relating knowledge but I just simply think that doing surgery on backbone is dangerous as we do on human brain)
(The hard voice once again interrupted me and said: You don't know then you have to listen to the one who knows it. He is telling you what you should know!!!)
D: I can insist that it will have 1/10 the difficulty of the first when the previous doctor put the frame into your body.
N: Could I ask you one question?
D: Yes
N: If I wont take the surgery in the future, what will happen? Will I have to use the wheelchair to move around?
D: Who told you that?
... (I started to feel the tears running on my face ... )
... (The doctor stopped talking ... and I heard someone ask if I had any family members coming with. The one they wanted to comfort me at that time was the one they refused to let her come in the room with me at the beginning.)
D: Who told you that things? Now we have to move the steel frame, and by the time the wound of the surgery heals, we will be able to take the MRI (Magnetic Resonance Imaging) to see clearly what is happening in your body. I am not sure about the steadiness of your backbone some years after this operation but the operation might stop making your leg weaker even by some physical exercises.
D: Are you clear?
N: Yes...
D: Now you should have your decision about it...
N: ... (Gave thanks to them in tears and walked out of the room ...)
