User avatar Hello,

Sorry for the delay in response.

To start with, I would advise a Doppler US on both lower limbs.

Being recumbent in bed for long time, may predispose to DVT which give a very similar picture to what you have described. The condition needs urgent management with anticoagulants.

This ulcer is known as pressure ulcer(decubitus ulcer), individuals who cant move from bed for long time , need special care for their skin and to change posture from time to time and to use special types of matrix to avoid these complications.

Surgical Consultation is essential.
