I've had this lesion since March 2017. It felt painful like a pimple when I first noticed it but the pain went away the next day, I tried removing it on my own using a baking soda method I read online. It scabbed, healed , and grew back. So I left it alone. June 2019 I scratched my back and accidently knicked it. It bled a little, scabbed and healed. I don't think it has grown, it looks to be the same shape and size it's always been. But the color looks darker. I visited a GP who said it didn't look worrisome and it's rather small (about 3.5mm)... As a form of habit I constantly take pictures of my mole and rub at it to see if there is any pain. (there isn't) but I have noticed today it looks to have 2 spots in it. I have made an appointment with a dermatologist but it's not for another 3 weeks. Does this look like a melanoma? I have no family history and I never burn in the sun. I'm scared. I have 2 kids to care for. First photo is taken in March 2017 second was taken today (8/8/19)
