I have woken up with discolouration on my finger tips. it's a light brown 'dirty' colour. i have a bad habit of biting but this hasn't happened before?

Monitor: Doubt it is related to a medical problem if you have no other symptoms. Most likely related to something that your fingers touched. If persists or spreads see a dermatologist
