If Tylenol is not effective for treating arthritis in your neck, you may want to consider trying an anti-inflammatory medication such as Advil or Voltaren gel. It would be best to consult with a pharmacist to determine if these medications are suitable for you. In addition, there are specific exercises that can help strengthen the muscles in your neck and reduce pain. You could also consider consulting a physiotherapist for further assistance. In some cases, prescription medications or cortisone injections may be necessary to alleviate the pain. It is important to discuss these options with your doctor.
