Can vaseline be sufficient to help with dark rashes and soreness on elbows and knees?
Patient: Just want Diagnosis Of Skin problem it's around My Elbow Joints and Above My Knee Joints at Present Time . On My Elbows It Feels Like a Carpet Abrasion where It's Sore and Tender When I rest my Elbows on mY lap or on Arm of Sofa Chair.  Real Slight Soreness on top Of Knee Caps , just Noticed very small dark rash. I put Petroleum Jely Vaseline on it now , seems to help , but it comes Back after a Day or two . Can You Diagnois What it Could Be ? Thanks Doctor: HiYou seem to be developing a frictional dermatitis over the elbows and knees.It can lead to pigmentation as is happening in your case.You need to avoid friction to the above areas as far as possible.Keep the elbows and knees moisturized.Using Vaseline is a good idea.But make sure you prevent any further friction.For pigmentation, using a kojic acid based cream would be helpful.Dr Geetika Paul
