A member asked:

Knee dark brown for months now . dr says it was sun burn? =summer+driving what else is it? the whole knee dark still months later. i don't buy it.

A doctor has provided 1 answer

Unsure: A tan can take a few months to fade, but the longer it stays, the longer unlikely from a sun exposure, but will not fade if repeted sun exposure. As is onlyone knee, something is causing the skin to darken-whether sun or another irritant, but seems like an outside job, not from within.
