Brief Answer:
Dermographism is not at all communicable.

Detailed Answer:
Hello,

Welcome and thanks for posing your query to the forum. I can understand your concern for dermographism since last 5 years.

Before I precede further let you understand the problem. To tell you medically - Our blood contains multiple type cells including red blood cells and white blood cells. Specifically these white blood cells provide immunity to our body which is of further multiple types.

Whenever anything in body is not suitable or offending to body then the number of white blood cells increases transiently. Particularly these cells which increase are eosinophils and basophils which are also known as mast cells. These cells contain granules which have a specific chemical known as histamine.

So as soon as any offending factors come in contact there is bursting of the mast cells. Therefore this histamine is released and we experience variable degree of itching and the kind of bumps which we can see in your case.

The bumps can remain for a very transient period to upto multiple hours. It can remain for more than 12 hours too depending on the intensity of the offending factor but never more than 24 hours.

There are multiple types of offending factor including our food, environmental factors including temperature variation, heat, humidity, cold, dust and even simple of fragrances in air and multiple of other related things.

In your case as these are present mainly after pressure which we call as dermographism.

For the treatment part - it is quite simple and treated with drugs which inhibits the histamine release also known as Antihistamines. The treatment provided to you is excellent.

For the part of your further queries:

1. It is totally unpredictable to know the exact duration of this condition. It may last from few months to innumerable years.

2. There is no side effects of the cetrizine. it is quite safe medication and can be taken for years together without any side effects.

3. It is not at all communicable. It can not be spread from one person to other so do not worry about the same.

I hope this information will help you in dealing the condition better. If you have any further queries I will be glad to help you.

With good health wishes,
