I have been getting a rash covering most of my body every time I get the slightest bit sick over the past 10 years. I have been told it was autoimmune and probably cause from when I got a almost deadly case of the bird flu. I don’t have any itching with it it just makes me look like I have the plague when it’s active. It effects everything except my face so that’s a plus but I’m beginning to wonder if it’s really that or maybe something else. The doctors never did any test when it’s active they just shrugged it off as autoimmune and that’s all.
