I came down w/a rash after spending my first night @ a hotel- 7/21/16. (Out of town in Md.) I woke up scratching/itching and rashes on my knees and the backs of my legs. After 3 days, consulted hotel about my problem and for them to check for bed bugs. None found? I then went to a Mini Clinic and showed her my legs and new rash on upper arms. I was diagnosed w/allergic contact dermatitis and prescribed Tramcinolone. I returned home on day 6 and made an appt. w/my dermatologist for the next day. She diagnosed me with Urticaria-acute. I was to take 4 Zyrtec in the morning and 1 Benadryl at night for 1 wk. I saw her after a little over a week, rash was practically gone,but I was still itching. She then referred me to an Allergist. 8/22/16-Exactly 1 month of the rash, looked at pix of my legs and showed me pix on the Internet of bed bug bites. He said that s what I had (bb bites) and Atopic Dermatis too. 8/22- I was told to take Allegra 2x/day for 2 wks, along with a sheet for clothing, soaps, detergents, etc. I am a Type2 diabetic. I have never experienced anything like this. What is wrong with me? Thank you for any help you can give me.
