My sister has the same problem when she gets it. She is allergic to it. You need to find a different doctor and get her on steroids and antibotics, I know youy said that she has been on them. But find a good doctor and tell them all about it. My sisters got so bad the first time that it git in her blood stream they almost had to put her in the hosp. SHE sees dr perez of premed phsycians I hope that helps.... Goood luck
