Last summer after sitting outside on a
summer night I noticed pinpoint sized
blisters forming a line on my upper hip on
the back side. It became itchy and
swollen forming more blisters and was
bright red all around. It eventually went
away but it has came back maybe like 3
times since last summer in the same spot
but not neccessarily in the same pattern.
It has just came back and the blisters are
in a cluster a little smaller than the
size of a dime but the redness and
swelling is about 3 times as big. Please,
any ideas on what this is? Thanks.
