Thank you everyone for your kind words I believe the reason it has come back is because last Oct I was sprayed with an ABC fire extinguiser and after breathing it into my lungs my body went crazy. As for the thymus returning that is possible as my thymus was spread throughout my chest and back then the Dr did say if he didn't get it all it could return. I have been in and out of the hospital alot since last Oct but I don't remember if they checked to see if thymus returned although I have had a chest cat-scan they were more interested in checking the lungs, I will have my Dr. look it over again. Once again, thank you for being here
