Hi IDBGCOLEMAN, Thanks for all your answers, I still have some more questions, and I need your help on how to approach the Dr. in the FFC for getting tested for viral infections??? You mentioned in your last note(answer), that you were tested for virals 3 weeks after you started on heparin, and the T3 thyroid, etc... Well I am starting my 4th week today, and my telecon appointment with my Dr. is on Oct. 3rd. I am not feeling better (may be tiny winsy). What shall I do?? Thanks so much, Defibro..
