You are all so great to give advice and join in. Like you said--it's nice to have company and not feel so all alone. So..what do we watch for with our lab work? I know it's a balancing act with Synthroid to have our levels "just right," however I can't even remember what is a good sign and what is a bad sign. I'm having my Thryogen on 5/12+5/13 and then the tracer dose on 5/15 and the WBS on Friday. I've been on the LID for 3 entire weeks! I'm very nervous about this scan for fear they will find that the cancer has spread. Knowing you all are there and understand is a great comfort. Is Tall Cell curable? Anyone know if we have to be isolated from others for the tracer dose? Thank you! Tara
