[|Human|] During the evening, mainly, my back starts to itch terribly. What causes this? I am now sitting at my desk and or an unknown reason, which is strange, my back is now itching. It is because I drink mountain dew sodas? I am a 3rd year doctoral student who works full-time, and take care of two sisters who are ill. I thought it was because of the stress I m dealing with; but need to know how to resolve the itching. Also, I have bumps on my back and top of arm. I m a 59 year old African American female.
[|AI|]  Hi, Thanks for your question. After going through your question there may be following possibilities for your symptoms of itching and bumps over back - 1) Allergic reaction to some foodstuff, environment or to insect bite. As your symptoms start abruptly this is most likely cause. 2) Fungal infection which is rare possibility as your symptoms started abruptly. 3) Scabies most rare cause. In this case some family members may have similar complaints. Try some antihistamines like cetirizine or HY Chat Doctor.  Apply lactocalamine lotion. Watch for symptoms like breathing difficulties, swollen lips. If there is no relief or started appearing new symptoms better to consult dermatologist. Hope this helps you, if so do vote.
