Splenic cyst, acupuncture

I would leave that to your practitioner and if your practitioner doesn’t practice herbal medicine, I would probably switch practitioners. That said the cysts are often encapsulated with scar tissue, or at least inflamed tissue, so there at times when it looks the same or perhaps even larger it is changing in a positive direction. In short, measurements are not a great indicator of what is actually happening below the scenes (within certain parameters certainly). But it is important to keep an eye on it.

The reason herbal formulas are best prescribed by your practitioner who knows your history, etc. and not because you have a cyst, is that they are based on your deeper diagnosis, not on your symptoms. Only they can really know what that is. Generally speaking you are using blood stasis moving formulas or a combination of that with other bases tailored more to your overall diagnosis - possibly qi deficiency formulas.
