Hello, I am wondering if I should go and see a doctor. I am staying with my inlaws right now and as soon as we arrived 6 days ago I got some sort of rash on the inside of my arms. It appeared after I had a nap on their fold out bed. Although I dont seem to have any allergies I do often have itchy eyes, a runny nose and sneezing when I sleep there. Now I dont have any of those symptoms but I do have the rash which itches intensely and it seems to be getting worse. It now looks like I have mosquito bites all up the inside of my arms, around my armpits and up the sides of my torso. My back is also itchy as well as my tummy and under my breasts but there are not as many visible spots. Does this sound like an allergic reaction or could it be something contagagious? Should I go to the doctor since I have had this for 6 days? Besides the itching I am not really affected. Thank you

Hello, Thank you for writing to us. House dust mite allergy is a likely possibility given the itchy eyes, runny nose and sneezing. Urticaria can happen (itchy hives) sometimes due to the dust allergy but usually unrelated. You will need skin prick tests or specific IGE blood test to find out what your allergies are (aeroallergen panel). Long acting antihistamines like cetirizine 10 mg or fexofenadine 180 mg plus Flonase nasal spray 2 spray/nostril twice daily is recommended for severe house dust mite allergy. You will need to take both for at least 2 months to have a good effect. The antihistamines will also work for the urticaria. I hope that was useful. Best Wishes.
