Late last year my knees developed brown patches of discolouraton on and next to to them which isnt going away. Is this a normal non ME/CFS thing or is this abnormal? (the dark patch which I had across a foot top and going to the bottom on the top of my leg and also over one ankle a bit which lasted for about a year, has thou disappeared and instead Ive now got this). Could this be venous stasis? http://skincare.lovetoknow.com/Skin_Discoloration Is this normal? or should I be trying to go and see a dermotologist?
