<unk> s are costly to treat, and there is a significant chance that they will recur after healing; one study found that up to 48% of<unk> s had recurred by the fifth year after healing. However treatment with local anaesthetic endovenous techniques suggests a reduction of this high recurrence rate is possible. Without proper care, the ulcer may get infected leading to cellulitis or gangrene and eventually may need amputation of the part of limb in future. Some topical drugs used to treat<unk>  may cause<unk>  eczema.
