I have been ichying like crazy, for 3 weeks now, I have small white bumps that come up in atlest 20 or more that ich VERY BAD. And the bumps arent red but the skin around it is, where ive iched. And now there are scabs that are bumps on my legs and back where I ich them so bad an the next day there red and scabed over. But when I ich theres notting there and then I will ich for a second and then 20 to more white bumps pop up and then I will stop I ichying and they will go away. What is this . I dont know if its hives cause I havent changed anything and I have always had a pet for yrs and been fine, and ive been on the same meds for years and have never had this till now.
