Sode effects

I suffer from migrains and I have received 3 injestions of Lidocaine, I think.

Is this the correct name for what I have received. It seems to me that is was Lidocaine and some othe pain killer. If this is correct, can you please tell me what kind of reaction my body and mind should have or could have.

I have experienced, crying, laughing, slured speech, body feeling heavy and deep sleep. Is this typical.

Is this is the correct injection what would the other pain killer be given along with it?. I ahve also received Nu-bain injections. However the Lidocaine seems to work best.
