What causes itchy rashes all over body that spread on scratching?
Patient: I ve been breaking out in rashes over various parts of my body over the past four weeks. The rash is itchy and seems to spread if I scratch it. I have dry skin and had been taking extra vitamin D which I stopped taking about 8 days ago. I still have the rash and while it may get better at times, it gets worse at times too. I am a 55 year old female in good health but I do have sensitive skin. I use all perfume free products. Doctor: Hi, sometimes rash can be a histaminic reaction to something we eat. A course of anti allergic medication like Fexofenadine plus Omeprazole for a week will help--regards
