Strain: If you're having most of your discomfort with turning your neck during daytime activities, wear a soft cervical collar but take it off at bedtime. If more discomfort in bed, wear it for sleep mostly. Try cold alternating with warm moist applications,take anti-inflammatory medication like Advil or Aleve, rub in liniment like bengay. See an MD if not improved after a week or sooner if symptoms worse
