I HAVE SKIN RASHES THAT RESEMBLE POISON OAK WHICH IS COMMON WHERE I LIVE. BUT I VE BEEN EXPERIANCING RASHES OFF AND ON FOR OVER A MONTH NOW IN THE SAME AREAS OF MY BODY. SEVERE ITCHY RASH WITH BLISTERS IN THE INNER CREASE OF MY ELBOW, BEHIND MYNECK AND EARS. CANT BE POISON OAK AFTER A MONTH. I m a 58 year old female who still has night sweats due to menopause.
It is a fungal infection.  Start using Candide ointment regularly twice a day.along with it maintain proper hygiene and keep cleaning the area with proper antiseptics.
