I am 18 years old and am having urinary issues. i am having a tube shoved down my penis and do not want to get anesthesia. is it really painful?!

Not that bad: It's over in seconds, and not as bad as you might think. Something along the lines of having blood drawn from your arm, or a shot of dental anesthesia.

Uncomfortable : Have them inject Lidocaine gel before the catheter and it should help. There are really no sig side effects from Lidocaine except for allergy perhaps.

Local anesthesia: They can place local anesthesia in the urinary tract which can help.

Local Anesthesia: Most urologists will use local anesthesia to help with this procedure. This is not a painful, but is somewhat uncomfortable procedure.
