Do I have hives? What is this?
I arrived in Maine on Tuesday, June 10 to visit grandparents. They have outdoor cats but I have been her many times before and nothing like this has ever happened.
Yesterday, I started getting little itchy bumps of what I thought were mosquito bites. They looked and acted just the same. They itch, I scratch, and they stopped itching after a while and shrunk down. But more and more are popping up everywhere! On my ankles, elbows, hip, back, neck, legs, knees, and arms! They itch sooo bad and now they swell up so badly! One of these bumps is right next to my knee, and its as big as my knee cap! My whole ankle is swollen! I think these happened shortly after I went to the beach! But I didn't go swimming, I collected some sand and shells. Ive tried benadryl creams and gels and they only last a few minutes!
What is wrong with me? What are these?
EDIT:
I should also add that only my joints, except for a couple bumps on my arm, are being affected. About a year ago my hamster bit me and there has been a hard spot there ever since and it had never really bothered me, but now it hurts!
