I was lied to

Recently, I went to see a doctor for treating about my backache, and he gave me a shot in my hip!!!
Before he gave it to me, I asked him before I was given it, "Is if it would be painful ??" and he answered , " yes, but only for the first a few seconds."

In a written conversation, we use a new paragraph for each new speaker. I've changed the sentence to reported speech, because that's more economical.

Actually, he had lied.

It was the hardest one I have ever got!
I was screaming during the whole injection!

Good effort! Shot is a bit colloquial, so we also use injection.

I know I've given you some upper-level grammar, but this is what we naturally use. Your original text is understandable, of course. :)
