I have a dark bruise like mark on my fae that comes and goes. I have never been hit there. What is causing it and how can I get rid of it.

It could be a vitamin C deficiency.
A vitamin K deficiency can also cause it but if you are taking medicine for your blood, like warfarin or cumadin you have to check with your doctor. If you are taking the drugs for your blood you have to be careful about eating salads and vegetables too.

It may also be deficiencies of other vitamins and minerals too.

Check with the doctor to make sure you don't have any health problems that could be causing it.
