Changes

*The second type of swelling is known as ''agantuja'' (exogenous) in which the etiological factors are extraneous, which could be physical or environmental. Many times they circumvent the routine disease courses and cause diseases in a very short course of time. Conventional involvement of ''doshas'' take place later on i.e. after manifestation of disease.

In addition to the types of swellings mentioned by Charaka, Sushruta has added ''rakta''based swellings as a separate type. [Su. Su. 17/4]. Sushruta has also emphasized on ''vishaja'' (caused due to poisons) as another type while mentioning treatment. [Su. Chi. 23/3]. Vagbhata has differentiated types based on causes of injuries (''abhighataja'') and contact with poisons (''vishaja'').  Further he has mentioned two types of ''shotha'' on the basis of distribution in body i.e. ''sarvanga'' (generalized) and ''ekanga'' (localized). According to its manifestation he has described three categories i.e. ''prathu'' (diffused spread), ''unnata'' (elevated) and ''grathita'' (nodular) [A.H. Ni. 13/22, 23]. On the basis of prognosis, Madhava has divided ''shotha'' into three i.e. ''urdhvagata'' (in upper part of body), ''madhyagata'' (in the middle part) and ''adhogata'' (in the lower part) [Ma.ni.-36/17]. These types are of clinical importance since they help understand the origin of the swelling and the pre-dominant ''dosha'' involved in it. [3]
