Smiling. Oh the amount of blood they have taken! My EB numbers were all over the place with each test. No one from the practice (in a university) has explained why that would be. I did lots of reading on my own and am guessing that it's likely that yes, they are reactivated and then "relax" (don't know another word for it!) and then re-activate again. I'm guessing the reactivation is when my mouth and more, my leg, are more actively "rashy". It's too much (time, energy and I'm waiting for Medicare to say too many blood tests) to keep getting tested and I'm not being told what to do. Do please tell me why you asked and what you may know. I keep seeking any information to be a more informed LC patient. THANK YOU, @diverdown1 .
