I have just been diagnosed with chronic idiopathic urticaria and am progressively getting worse despite double doses of antihistamine. I just did a 48 hr detox diet and am now doing gluten free, lactose free (I'm lactose intolerant), and histamine restricted diet. How long did it take for you to see improvement in your symptoms? I've gotten very little help/direction from my PCP or dermatologist and am wondering if I should be pushing for further testing or should I stick with the diet and wait for my recheck appt in 6 weeks? Any advice or thoughts are appreciated!
