Traditional Chinese medicine believes that all pains are solid, and all itching is deficiency. The meaning of this sentence is that pain is often a manifestation of empirical evidence, while itching is often a manifestation of deficiency syndrome. In traditional Chinese medicine theory, empirical and deficiency syndromes are two different pathological states. Empirical evidence refers to the excess of evil energy, the absence of decline in positive energy, and intense competition between evil and positive energy, manifested as symptoms such as pain and swelling; And deficiency syndrome refers to the weakness of the righteous qi, the lack of vitality of the evil qi, the lack of intense competition between the righteous and evil, manifested as symptoms such as fatigue and itching.
中医认为，诸痛为实，诸痒为虚。这句话的含义是，疼痛往往是实证的表现，而瘙痒往往是虚证的表现。在中医理论中，实证和虚证是两种不同的病理状态。实证是指邪气亢盛，正气未衰，邪正相争激烈，表现为疼痛、肿胀等症状；而虚证则是指正气虚弱，邪气未盛，正邪相争不激烈，表现为乏力、瘙痒等症状。
