White Welts On Skin
Multiple causes: Welts or hives on the skin are usually triggered by increased allergy cell activation (mast cells) that release histamine. If present for less than 6 weeks, they can be secondary to medication, infection, food, or sting. If they last greater than 6 weeks, there is often no known cause or there can be an autoimmune etiology. ...Read more

Dermatographism: Welting of the skin immediately following rubbing is called dermatographism or dermatographic urticaria (medical word for hives). It suggests that a cell population in your skin, called mast cells, are releasing histamine. It is seen in 4-5% of people. In most cases a cause is not discovered. If it bothers you, try antihistamines like zyrtec or Benadryl (diphenhydramine) (check interactions and contraindications). ...Read more
Dermatographia: Some people have really sensitive skin. If you scratch your skin, you will get a raised rash on the affected skin. There is nothing to do about this, aside from taking benadryl (diphenhydramine). Try writing words on your skin with your fingernails. If it works, you have sealed the diagnosis. Hope this helps! ...Read more

Dermatographia: It sounds like you may have a condition known as dermatographia (literally "skin-writing").

You should be evaluated by a dermatologist or allergist. ...Read more
