Doctors opinion on red itchy swollen rash all over entire body?

My cousin noticed that her ears started becoming swollen and itchy, then a rash formed from the ears to her neck to her breasts. She woke up this morning with the rash all over her face, swollen lips, ears, arms, wrists, legs, thighs and feet. We’ve been trying to think of what it could be and research says it could be chemicals? she has been to visit her dad who works in a mechanics and this could be the reason? She has not eaten anything different, havent touched any poison ivy etc. Any idea of what it could be and what to do?

I suggest your cousin visits a Dermatologist asap.

Think you should visit your doctor asap – in the mean time take piriton or another anti histermine as it will help if it is an allergic reaction or heat rash.
