CHAPTER 52 Joint Pain after Childbirth
Aetiology
Severe blood loss during labour
Profuse blood loss during labour leads to severe Blood deficiency after childbirth: the deficient Blood fails to nourish the channels and the sinews and this causes a dull ache of a deficient nature.
Invasion of external Wind
External Wind may invade the channels and settle in the joints causing Painful Obstruction Syndrome: a woman is more prone to such invasions after childbirth because the channels are in a weakened state due to Blood deficiency and the space between the skin and muscles is Empty due to Qi deficiency. Wind usually combines with either Cold or Dampness or both to cause joint pain. If Wind predominates, the ache will move from joint to joint. If Cold predominates, there is intense pain, and if Dampness predominates, there is numbness, tingling and a feeling of heaviness of the limbs.
Emotional problems
Emotional problems such as irritation, worry, frustration and resentment cause stagnation of Qi which, after childbirth, may easily lead to Blood stasis. Blood stagnating in the channels, especially in the joints, causes joint pain of a stabbing nature.
Weak body condition
If a woman suffers from a pre-existing weakness of the Kidneys and Liver, this will be exacerbated after childbirth. The Kidneys influence the bones and the Liver the sinews, and these two tissues will lack nourishment: this will cause a dull pain of a deficient nature in the joints and especially in the lower back and knees.
Pathology
The pathology of Joint Pain after Childbirth can be differentiated according to whether it is of an external or internal origin. When joint pain after childbirth is due to invasion of Wind, it is of external nature and its pathology is essentially the same as that of Painful Obstruction Syndrome.
In the other cases of Blood deficiency and deficiency of Liver and Kidneys, the joint pain is caused by malnourishment of the channels, sinews and bones. Blood stasis, caused by stagnation of Qi and Blood in the channels, is always painful; the principle is that ‘obstruction causes pain’.
From the point of view of deficiency/excess, the pain from invasion of Wind and from Blood stasis is of an excess nature, that from Blood deficiency and from Liver and Kidney deficiency is of a deficient nature. Pain of an excess nature is severe and stabbing if caused by Blood stasis; intense, fixed in one joint and cramping if caused by Cold; dull and with a feeling of heaviness if caused by Dampness; and dull and wandering from joint to joint if caused by Wind; it tends to improve with activity. Pain of a deficient nature is more like a dull ache and it improves with rest.
Identification of patterns and treatment
The treatment principle must be clearly differentiated according to the pathology. In deficiency cases, the primary aim is to nourish Blood, tonify Liver and Kidneys and benefit sinews and bones; the secondary aim is to expel Wind, scatter Cold and resolve Dampness. In excess cases, the primary aim is to expel Wind, scatter Cold and resolve Dampness; the secondary aim is to nourish Blood. Even if the joint pain is from external Wind, it is important to nourish Blood after childbirth, because the deficiency of Blood renders the woman prone to invasions of Wind and because nourishing Blood helps to expel Wind from the channels. In cases of Blood stasis, the main treatment principle is to invigorate Blood and eliminate stasis.
