Heat rash (aka prickly heat) is uncomfortable but not dangerous. The little red or white bumps are caused by clogged sweat glands. If affected, wear lightweight fabrics & try to stay cool. Cool baths or compresses may help tame itch. Limit creams/lotions that can worsen blockages.
Poison ivy, oak, & sumac grows as shrubbery or on vines. The plant oil causes an itchy rash in up to 75% of people. The rash is not contagious, even if itched (although infection becomes a concern). Most rashes last 5 -12 days & can be cared for at home with over-the-counter creams/lotions as directed. Get immediate medical advice if you have trouble breathing or severe swelling; a fever or signs of infection; or a rash on your face, genitals, or over 25% of your body. Be careful-- contact with lingering oil on shoes, tools, pets, etc., can also cause rashes.Many types of insects & arachnids bite or sting like bees, chiggers, fire ants, spiders, etc., (plus last week's mosquitoes & ticks). Pain, redness, & minor swelling at the site is actually considered a normal reaction. These symptoms can often be relieved with ice, over-the-counter medicines, & creams/lotions as directed. However, anyone stung who starts to have trouble breathing, wheezing, hives, etc., should get immediate medical attention.
