Defendant argues that the district court wrongly instructed the jury on the meaning of bodily injury. Defendant did not, however, object to the jury instruction at trial. Thus, the court’s instruction will be reviewed only for plain error. See United States v. Thomas, 11 F.3d 620, 629 (6th Cir.1993), cert. denied, — U.S. -, 114 S.Ct. 1570, 128 L.Ed.2d 214 (1994).
The district court instructed the jury that bodily injury means any injury, no matter how temporary. Bodily injury also includes physical pain as well as any burn, cut, abrasion, bruise, disfigurement, illness or impairment of a bodily function.
J.A. 886-87. Defendant argues that the district court should have used the definition of serious bodily injury from 18 U.S.C. § 247(e)(2). However, 18 U.S.C. § 242 does not require serious bodily injury; it only requires bodily injury. Moreover, although bodily injury is not defined in § 242, it is defined in four other provisions of Title 18 of the United States Code. In these four provisions, Congress gave the term bodily injury the same meaning, providing that bodily injury includes “a cut, abrasion, bruise, burn, or disfigurement,” “physical pain,” “illness,” “impairment of a function of a bodily member, organ or mental faculty,” or “any other injury to the body, no matter how temporary.” See 18 U.S.C. §§ 831(f)(4), 1365(g)(4), 1515(a)(5), 1864(d)(2). The jury instructions given by the district court are consistent with the definitions of bodily injury used in Title 18. Further, in United States v. Myers, 972 F.2d 1566, 1572-73 (11th Cir.1992), cert. denied, — U.S. -, 113 S.Ct. 1813, 123 L.Ed.2d 445 (1993), the Eleventh Circuit held that jury instructions in a § 242 prosecution which defined bodily injury as “injury to the body, no matter how temporary, ... in-clud[ing] physical pain as well as any burn or abrasion,” were not erroneous. Accordingly, the district court’s jury instructions on bodily injury were not plain error. See United States v. Olano, — U.S. -, 113 S.Ct. 1770, 123 L.Ed.2d 508 (1993).
Finally, defendant argues that there was insufficient evidence that Archie suffered bodily injury. However, Archie’s testimony at trial was sufficient to establish that after both assaults she suffered bodily injury as defined above, beyond a reasonable doubt.

Defendant argues that the district court abused its discretion in failing to grant his pretrial motion to sever the trial of the three felony counts from the eight misdemeanor counts charged in the indictment. Defendant asserts that he was prejudiced because of the district court’s failure to grant a severance. He argues that if the two charges involving Vivian Archie, counts 6 and 7, had been tried separately, he would have been acquitted of those charges because Archie’s testimony lacked credibility.
A motion for severance pursuant to Federal Rule of Criminal Procedure 14 is committed to the sound discretion of the trial court. United States v. McCoy, 848 F.2d 743 (6th Cir.1988). A defendant making a motion for severance under Rule 14 has the burden of demonstrating a strong showing of prejudice. United States v. Goldman, 750 F.2d 1221, 1225 (4th Cir.1984). “To show enough prejudice to require severance, a defendant must establish ‘substantial prejudice,’ ‘undue prejudice,’ or ‘compelling prejudice.’ ” United States v. Warner, 971 F.2d 1189, 1196 (6th Cir.1992) (citations omitted). Further, it is not enough to justify a severance for a defendant to show that joinder has made his defense more difficult or that separate trials might have offered him a better chance of acquittal. Goldman, 750 F.2d at 1225.
In this case, the district court did not abuse its discretion in denying defendant’s motion for severance because defendant failed to establish either substantial, undue, or compelling prejudice. Accordingly, this issue is meritless.
C.
Defendant argues that the district court erred in failing to dismiss the indictment on the ground that the charges contained in the indictment were impermissibly vague. Defendant asserts that although each misdemeanor count in the indictment alleged a specific act of defendant, the counts also
