The reason for local anesthetic is because it's safer for the
surgery. the anesthetic is only needed around the area, in this
case it's your leg? so there is no point risking other part of your
body like your heart, brain, stomach, etc. Why I said risk? because
your nerves are practically "sleeping" during that, and "sleeping"
nerves are not good. When cell is 'idle', it doesn't really have
enough energy and enough oxygen. The risk? the cell can die.
Well,.. every second there are some cells of our body die, but
imagine if you have to bring down the whole body?
There are cases where without proper anesthetic, after the surgery
the patient couldn't wake up, hence they are in 'coma' condition
for ages. Some died. Why? because the dosage that is given is the
standard, which is safe to almost all people. But it is "almost
all" and not "all". Some people are unique, they body will react in
unique way and totally different from the majority. Hence it is
fatal to assume.
So,.. local anesthetic is your best option.
If you are really scared, tell the doctor. If he tries to make fun
of it and try to kid around.. say that you are serious (with a very
serious face like you are going to eat him).
When you lie down, you can ask them to cover your upper body and
head,.. or simply close your eyes. Try to think about something
else, or sing a song in your heart. If you are Christian, then I
would say prayer and worship will be very comforting. And just keep
one thing in mind during that: the doctor is the expert! he has
been facing the same cases for so many times, he is so familiar
with it. do you have any idea how many people go for surgery in one
day? how many patients he's dealing with in one month? you are just
one of many, he will be easily taking care of you.
About your study,.. as you recover, you'll be able to catch up.
Everyone knows first few weeks is the basic of the entire
semester's material. You can also ask your friends to assist you in
catching up. and if you are still worried, you can talk to your
lecturer (if they are 'ok' type) about your concern BEFORE the
surgery. Why before? so it doesn't sound like an excuse to fail,
and some more it will make you sound like a hard-studying student
who is concern about the academic performance. Lecturers love them.
