A while ago I noticed a patch of skin on my head that was slightly darker and shinier than the rest. Almost as if this one patch has been sunburnt or scalded- only it hasn't. I've just caught a glance of it and something made me worry a little bit. I don't think I was born with it. Started shaving my head around 4-5 years ago and noticed it maybe 2-3 years ago. I did have a case of enlarged lymph nodes at the base of my skull a good few years ago too- I don't know what triggered that, not sure if it's relevant. I've scanned around on Google and can't find anything. It's not itchy, flakey or anything. Really odd. It's just appeared out of nowhere.
