Skin - discolouration

Q: My aunt is having a discolouration of her leg skin. First her legs got swollen and later on they became dark brown in color. When the tests were done, clinical doctors declared her to be normal. Her leg tissues have tightened which does not allow her legs to bend. Suggest me what to do.

A:I think your aunt is having post inflammatory pigmentation i.e colour coming after a lesion has healed. It goes by itself. Just also check out that she has no problems with her leg veins (varicosity etc).
