Recently my skin got rashes and itching, then skin become red and sometime swollen. This mostly happened when I working in office.

I will wipe my desk and chair every time before start my work. I not sure is my working space is dirty or the office aircond is too cold.

Hope anyone here can suggest a good dermatologist in Klang valley, prefer near Cheras, Pudu, Bukit Jalil area which near my house. 

Try go pharmacy buy medicine called Centrizine to control rashed. This is very very safe to consume, 1 day 1 tablet. Can continue consume without any issue.

At the same time recommend you went to General Hospital dermatology department to check, before that, go to ur nearest KKM get letter to attend general hospital dermatology.
