[|Human|] My arms have been covered in an itchy rash for weeks!! Maybe its bites maybe a rash. It started on my upper arms, then moved down to the crook of my elbows. Does it sound like bites? Or something else? & maybe this would be important too- sometimes the redness & inflammation 100% disappears, but 100% returns 24 hours later
[|AI|]  Hi, Welcome to Chat Doctor, Itchy rashes over skin of arms and hands could be due to eczema, allergic hives, insect bite, atopic dermatitis, Tina corporal etc. The important thing is to diagnose first rather than treatment. You can go to skin specialist for detailed history and inspection of rashes to have a clear diagnosis. You might require topical corticosteroid like beclomethasone, clobetasol or mometasome with antifungal cream like fluconazole or itraconazole with antihistamines orally to reduce itching. Some time oral antifungal once dosage with prednisolone are also effective. So, you must consult to the doctor.
