May i ask if anybody knows ..

now, i've knew this skin allergy that always bothers me. i've searched the internet and i found out that the symptoms like what i've experience till now is that of demographia. a little stroke or scratch on my skin immediately form into rash, itchy, swell and reddish. i can even write my name in any part of my skin and then in an instant it is swelling, itchy and turn red. as far as i know this is not a disease to worry because right after the swell after 15-30 mins. it turns back to normal. although, i admit its bothering me. help me please...........

A good medicine which will control this is called loratidine (also known as Claritin or Allavert). You take it once a day and it suppresses the dermographia until the allergies have passed.
