I really need help everyone... My knuckles and elbows are DARK... has anyone experienced this and found a solution... responses are very appreciated...

Well I saw a feature in t.v. about natural cures to dark elbows and knees, and they said that rubbing milk dipped in a cotton ball over the area for a few minutes is effective because milk contains a certain ingredient that lightens skin. Since dermatologists were the ones saying it, I think you should give this one a try.hope this helps.
