<human>: I am awake at 4am because of a total body itching. Hands feet everything. It started yesterday morning and I took and antihistamine and it went away for a few hours but came back with a venegence this am. It seems like internal rather than external cause. I have been having stomach issues for the last couple months, with some cramps and nausea . Thought it was the flu but still feel slightly nauseous after I eat. Have noticed my urine is concentrated in the morning as well. Have had a few headaches in the last few days.
<bot>: Hello, It is possible that you are having infection-related urticaria (urticaria is red itchy weals that come and go; triggers: infection, stress, autoimmunity and most are spontaneous). You will need a complete blood count, CRP, Lots, urine c/s, stool c/s (if still having abdominal pains) to exclude an infection. Appropriate antibiotics and long-acting antihistamines such as fexofenadine 180 mg once daily for a week is required to control this. Sometimes you may need to continue on the antihistamines for longer. Best Wishes.
