Brown/reddish stain finger pads

For a number of years I get a discoloration on my left hand finger pads between little finger and index finger.

If I cut the skin it is not below first skin layer.  At first I considered it was stain from something I might have come into contact with.  I no longer think so.

If I wash the area the stain remains.  I can however get a great reduction using bleach or alcohol and a tooth brush.  The tooth brush does have a stain on bristles when finished.  But discoloration returns the next morning upon getting up from bed.

The stains seem to hang around for a month or 2 then goes away but does return.  Been going on for about 10 years.  Stains always appear at same location each time it returns.

I have researched the internet for months now not finding any answers.  I do not have the money to go to a skin doctor.

Any thoughts or suggestions would be welcome.
