RecruitingDevice studyHome-based Transcutaneous Auricular Vagus Nerve Stimulation (taVNS) for IBS PainThe goal of this clinical trial is to learn the feasibility and safety of using home-based taVNS in young adults with IBS to manage their IBS-related pain and symptoms. It will also learn about participants' experience in using the home-based taVNS intervention. The main questions it aims to answer are: * Is it feasible to use a home-based taVNS intervention for pain and symptom management among YAs with IBS? * Is it safe and reported satisfactory to use a home-based taVNS intervention for pain and symptom management among YAs with IBS? Researchers will compare Active to Sham taVNS (a look-alike intervention that contains minimal stimulation) to see if Active taVNS works on managing IBS-related pain and symptoms. Participants will: * Take Active or Sham taVNS intervention for a 6-week treatment (twice daily, 30 minutes per session) * Visit the research lab at the initial setup and the end of the 6-week treatment for checkups and tests * Keep a diary of their symptoms and the number of times they use the taVNS.
