I can honestly tell you that I know what fears and anxiety you are going through. Unknowing and waiting for answers is very difficult. I took lots of meds before my transplant, too. But I do not even remember what they were. All of those tests are giving a picture of what is happening inside you.. Many tests, labs, and scans will create an accurate assessment for your doctors to use in your treatment plan. If you are eligible to move forward to be listed, then you will assigned a pre-transplant nurse (at least this is the way it was at Mayo) and he/she will be able to provide additional support and direction. It sounds like you are headed to Mayo,. Is that right? Believe me, they will adjust your appointments and treatments to match your own medical needs. I hope you will have a better idea of what lies ahead after your appointment.
