Also, generally speaking, thyroid issues can come from several different diagnosis in Chinese medicine. If Kidney Qi is the root, it can take a long time and also require nutritional and/or herbal supplements. By long time, I mean SEVERAL months, usually at least 3 for someone in your age group.
I don't use acupressure very much. I've found that acupuncture using needles usually provides the quickest and longest lasting result.
I'd suggest starting with your primary care physician to determine exactly what is going on with your thyroid. This will usually involve some blood work and may involve ultrasound or other imaging.
Once you have a conventional diagnosis and understand the conventional treatment options in terms of risks and benefits, take your lab and imaging results to a board certified and state licensed acupuncturist (use the "Find a Practitioner" lookup at NCCAOM.org to find a local provider) and have them give you a consult to see if there's anything Chinese medicine might be able to offer.
