[|Human|] I am a 58 yr old married female. I have had two knuckles on my right hand that are very, very itchy, red, raised, inflamed. If I scratch them it feels so good while I am scratching then after its a mess. Redder, scaly, inflamed, dry. I thought it was allergy , so I stopped all kinds of things, but it has persisted daily. Much worse in last 6 months. Help!
[|AI|]  Hi, It's tough to tell without looking at the lesion but you symptoms suggest you may have psoriasis.  In this condition lesion is very itchy, after scratching you will see white powder like flakes, this condition becomes worse when you're in stress, then summer. You will have to visit a dermatologist .he will inspect the lesion and guide you further. Till then, you apply moisturizing lotion on it and take antihistamine for the itching. Thank you Chat Doctor.
