I noticed some itchiness and pink bumps some raised some flat on my back. some then spread near my chest area and close to my hip bone. am i allergic to something? the only thing i ate of concern was an egg some days ago. is this hives?

Did you have any pain a few days before the eruption occurred? An allergic reaction is generally a widespread rash unless it's a contact dermatitis from something that only touched the area of the rash. Shingles, A viral infection caused by the chickenpox virus, occurs in a line across one side of the body &is often preceded by pain. See your MD as shingles,if present,can be treated.
