7. Troubleshooting
If you experience issues with your Miami J Cervical Neck Collar, consider the following:
- Discomfort or Pressure Points: Re-check the fit and adjustments. Ensure the collar is centered and straps are snug but not too tight. Verify that the correct size has been selected based on your phenotype.
