Phrase meaning, please

Question

hello people-

I am having oral surgery soon and my friend told me I was "in for it"...what does that mean?

Answer 1

Your friend must have had a difficult time with the same type of surgery, meaning that it will be painful.  However, everyone has a different experience and you do need to expect some discomfort.  Dentists use a variety of methods and drugs to counteract any serious pain.  So don't be afraid and definitely don't let your friend scare you.

Answer 2

It means that it is going to be an unpleasant ordeal.  I can assure you however, if you are seeing a good dentist or oral surgeon, you wont feel much but the small sting of a needle to numb your mouth.  The rest is easy.  

Answer 3

Loosely translated, it means "it's going to be tough" !
