Are you providing acupuncture or acupressure and what is your training? I ask because it appears you are using only one point and do not have a clear TCM diagnosis of the patient overall. Acupuncture requires this to be properly applied.
If you are providing acupressure some points, even if they fit the condition well, do not respond well. So if I know your training and what technique(s) you are using I can offer more.
Without more details about the patient overall (say from the "ten questions", tongue diagnosis, and/or pulse diagnosis) it is difficult to offer anything definitive. In many cases these symptoms are the result of Heart Fire or Liver Fire, but Stomach Fire, or a pattern such as Kidney Yin Deficiency (among others) could also be possible. Proper diagnosis is key before treatment begins.
If you are using acupressure try HT 8 instead of PC 8 and LV 2 and/or LV 3 .
