Does the local anesthetic injection before a Vasectomy hurt?

I understand that there may be complications/pain/swelling after during recovery. I can manage that. I am very nervous about the procedure. Not so much the cutting because I will be numb, I am worried about the actual injection of the local anesthetic. I think I can deal with them going through the skin but how bad does them pulling and then injecting the actual tube hurt? Please fellas be 100% percent honest, I don't care if you are tuff I want the truth.
