Please tell me what can i do about a condition called 'stassis dermatitis'?

Chronic condition: Because venous circulation is impaired in the lower extremities fluid can back up and result in dermatitis. This most often shows up on the shins but anywhere below the knee is common. Compression stockings to help improve return flow can help as can treating the active inflammation with topical steroids. Regular follow-up with your primary doc and dermatologist are important also.
