I suspect that a spider bit me, how do i treat it?

Type of spider: This depends on the type of spider and the reaction you are having. Most small spiders cause only local reactions and can just be treated with symptomatic relief (for itching and pain, with antihistamine and acetaminophen, compresses). If you are having an enlarging or extremely painful skin reaction or difficulty breathing or swallowing, please be seen at an ER or call your doctor.
