What I did was change my diet, I took out all the food containing gluten.
Through months of experimenting though I still have this allergy, the itch is tolerable, It only itch couple of minutes then gone and sometimes doesn't itch at all.
And I also noticed that when I'm so stress they're showing up.
By that I've found out sleeping well could reduce the out-break.
And stress-tab really help, I don't know why, I'm no doctor but through reading every forum about dermographia, I've noticed that most of them saying, when they've first noticed the symptoms they've gone from eaither, taking antibiotics, infection, surgery and emotional trauma/stress. Are you guys noticed one of what I've mentioned
before you found out that you had this condition. On my case, I've got this dermographia after a series of antibiotics to eliminate bacteria/infection in from my blood.
