Chinese medicine identifies a pathogen called ‘damp” that can develop from both external factors, such as climate and diet, and also internal factors such as weakness of the digestive system. If damp is present, it is aggravated during periods of high humidity.
Pathogenic damp is obstructive in nature and leads to stagnation of blood and fluids, particularly in the joints which causes pain. It can also lead to feelings of muzziness, heaviness and cause oedema.
A trained Chinese medical practitioner can diagnose this condition and formulate a treatment plan to ease and treat symptoms over time and relieve pain. It is interesting to see how science is exploring how these pathogens act in the population, see article below from the BBC.
