Have Medical Questions? Ask a Doctor Online!
I still don't know why your questions are showing up twice but I will post my answer here in case you could not see the other:
Hello this is Dr. Salama MD,
Eczema is simply inflammation of the skin which can be triggered by change of weather, dust etc...
It tends to be genetic in nature and is commonly seen in those suffering from asthma or environmental allergies but it can stand alone as well.
Let me know if you have any other questions.
If not, please don't forget to leave a positive rating as that's the only way I get credit for answering your question.
