I've noticed on some of my toe and fingernails I've got thin black lines. No pain or anything but they're definitely there. I wondered if I'd hit them and caused bruising or bleeding but I don't think I have and it's unlikely I'd have it on my toe and fingernails.
Does anyone here know what this could be? I'm wondering if it's vitamin related. Maybe I need more dairy in my diet?
If you think it's more serious and might need further investigation then I'll call the doctors but my anxiety is so bad I can hardly leave the house. So doctors are a last resort. If anyone knows what these black lines are your Insight is welcome and thanks:)
