Hello! I am a 36-year-old female with multiple food allergies and a history of seasonal allergies and Hashimoto’s thyroiditis.
Since roughly November, 2016, I started noticing that I would randomly become very itchy. The itching starts at maybe my foot/leg, ears or arms/hands and spread throughout the day to my torso, back and basically any other part of the body you can think of. If I take loratidine OTC 5 mg., this will calm the itching temporarily. Within 48 hours of taking the pill, the itching returns. My allergist originally diagnosed me with dermatographia, but the itching seems to begin regardless of whether or not I have been touched, scraped or bumped by anything. It will occur randomly, as I sit at my desk at work, or watching tv. But it will also occur if I’m exercising. There is usually no rash, except for bumps that come from my harsh scratching response, and I usually bruise myself from scratching so much and so hard. I suppose I could take loratidine every day, but I want to get to the root of what is causing this maddening itch in the first place.
Does this sound like anything anyone has heard of before? This is an entirely new symptom for me, and doesn’t seem to have come at the normal time of my seasonal allergies (started in November). Any advice/help is appreciated, so I can bring this concern to my allergist in September.
