- Aetiology: Due to excessive intake of cold, hot, liquid, very dry, heavy and fatty food, without taking care if the previous meal has been digested or not, or also tiredness due to excessive physical work, great stress, day sleep or wakefulness vaayu in association with too much of accumulated ama dosha, kapha and medas overpowers the other doshas and migrates to the thighs and fills up the musculo-skeletal system of the thigh with the moist kapha. As a result, stiffness of both the thighs occurs which is called urustambha.
- Clinical features:

- Aggravation of the disease:
On account of ignorance, if people mistaking it for a vaataj disease, apply oleation, languor and numbness gets exaggerated and the capacity of lifting the legs is further reduced. There is excessively apathy to use the calf muscles and the thighs. There is a constant burning sensation and pain.
The urustambha would prove fatal when the patient is distresses with a burning sensation, pain, pricking sensation and tremors; the condition should otherwise be treated as also if it is of a recent onset.
Aetiopathogensesis: When a person with sedentary habits with hypo functioning digestive mechanism indulges in incompatible diet and regimen, or does physical exercise after taking fatty food, the ama is formed and is propelled by vaayu which reaches the site of shleshma. The aam rasa, on being incompletely processed and very much vitiated by vaat, pitta and kapha is circulated all over the body through the vessels. It then takes on multiple colours, becomes excessively mucoid and accumulates in the small channels. It renders the patient weak in no time and produces a feeling of heaviness in precordial region. When this aggravated ama simultaneously afflicts the pelvic and shoulder girdles and other joints making the body stiff, the condition is known as aamvaat. Clinical Features:
- A feeling of heaviness
- Inflammation of the body parts
Features of doshaj predominance in Amavaat:
- With the predominance of pitta, there is redness and heat locally.
- Whereas with the predominance of vaat, there is severe pain in the joints.
- If the kapha is predominant, a feeling of being covered with wet clothes, heaviness and itching sensation are present.
Prognosis: When one dosha is involved, the disease is curable; with the involvement of two doshas, it is said to be relievable only. When all the three doshas are involved and there is an inflammation all over the body, the condition is difficult to treat.
