Yesterday I was outside and a dog had gotten in the trash and dragged out a pizza box. I picked it up and went to throw it away. When I got to the trash can I felt a pin prick on my hand. I looked down and there were about 30 ants on my hand and arm. I quickly brushed them off but not before I was bitten about 10 to 15 times. Today my hand is killing me itching and swelled its very hard to type or do anything. I have taken some Benadryl and put Caldryl cram on it but nothing seems to help. If you know what to do let me know. I am going crazy from the itching.
