Around 2 months ago I started getting flea bites and a month after that I developed a dry rash around my neck. Later on I started getting this pink itchy patches along my lower spine as well as my pelvic area. I've been to 2 doctors and both aren't sure of the cause, one believed it could possibly be a seasonal allergy. I've been taking reactine and it has helped with the itching but whenever I stop taking it the itching comes back. The patches aren't dry and turn a darker brownish tone when I don't itch. I haven't been taking any other new medication or have eaten anything new. I also don't have a history of seasonal allergies.
