It started three days ago on the nape of my neck one morning when woke up, at first it was mild itching with tiny pink bumps... and
then the itch got worse and
worse... then similar cluster appeared
on my left upper arm--along with the same type of rough pink red
dish bumps. My right upper arm is not affected (at least not yet).
A couple of hours later the itchy
bumps appears on my upper back with pink red
dish rough hard bumps all over...
