I did my ovidrel shot last Wednesday and the next day I developed a rash and it's just getting worse. I can't get into the doctor till this Wednesday and it's killer. I am taking Benadryl which isn't helping a ton and I am thinking its hives but they just keep spreading. They started at the top of my thighs and are not covering my entire upper leg on both legs. My husband said it feels like he is reading braile on my legs! Bumps are everywhere!!! I have used Benadryl, cornstarch, ice. Nothing helps!!! Has anyone has this reaction or know what to do?
