[|Human|] My hands keep itching, and when i scratch them a small raised white lump appears, after a while a whole lot of them will appear over the surface of my hand, the itching will then stop and the lumps disappear, they come back around 3/4 times a day, what could be causing this?
[|AI|]  Hello and welcome to Chat Doctor, The appearance of lumps on hands after itching suggests an allergic reaction. Itching is causing the bumps to appear on the hands. Is there history of exposure to any allergen like some metal, chemical, or some environmental allergen? Or do not symptoms appear seasonally? These allergens can elicit an allergic reaction and cause itching. However, a clinical assessment is required to assess the type of lesion. If allergic antihistamines treatment will be helpful to relieve the symptoms. Thanks and take care Chat Doctor.
