The majority of cases of venous insufficiency involve the circulation in the lower limbs, and while there is very little specific western research on this, we have to remind people that Chinese medicine has dealt with problems liek this for centuries, and has a number of treatment strategies for problems in which this is one of the symptoms.
It is important to be aware that Chinese medicine operates from an entirely different conceptual basis in which the flow of energy, called 'qi' in Chinese, is central to the effective flow of all body fluids and to the overall balance of the system. The practitioner of Chinese medicine uses his or her skills to try to determine how the system is out of balance and then devises treatment strategies to correct imbalances. In some cases this is symptom led, and in other cases, the treatment is much more general, aimed at correcting the overall balance premised on the simple belief that when a system is in balance, symptoms repair themselves.
The best course of action is to visit a BAcC member local to you to seek their advice on whether your particular case makes sense from a Chinese medicine perspective and what they would advise. In many cases acupuncture would be an appropriate treatment, but there may be other options which a practitioner may recommend as better suited for what specifically troubles you.
