Symptom Tracking & Assessment Tools
The MSIDS Questionnaire: Digital or Printable
The FREE Printable Horowitz Lyme-MSIDS Questionnaire, created by Dr. Richard Horowitz, helps identify Lyme disease and related infections by assessing 38 symptoms in infection, inflammation, immune dysfunction, and environmental factors. It scores symptom frequency and severity to highlight underlying causes, especially when standard tests are inconclusive. Patients can complete it alone or with providers to guide testing, treatment, and specialist referrals.
