The presence of marked edema and severe bruising on one side of the episiotomy, combined with severe rectal pressure, strongly suggests the presence of a vulval hematoma. A vulval hematoma can occur when blood collects in the soft tissue of the vulva, typically due to injury to blood vessels during childbirth. The significant swelling (edema) and discoloration (bruising) are characteristic signs, and the pressure experienced may indicate that the collection of blood is large enough to compress surrounding structures, causing discomfort and potential complications.

This situation typically arises from trauma sustained during labor and delivery, which may not always be immediately obvious but can develop shortly after birth. In this context, the other options do not adequately account for the specific combination of symptoms present. For example, while an episiotomy infection could cause discomfort and swelling, the acute nature of the bruising and pain alongside rectal pressure points more towards a localized collection of blood rather than an infectious process. Similarly, soft tissue trauma could represent broader tissue damage but would not necessarily explain the localized effects observed here as distinctly as a vulval hematoma. A hematologic disorder could lead to bleeding issues, but the specific signs here are more consistent with a localized hematoma rather than
