Have you contacted the hospital about your throat? I am 49, 7 years post SCT and if I feel a cold starting to take hold I get on to the Dr or hospital for treatment, the head consultant at St.Hellier told me to do this in order to prevent a cold progressing to pneumonia which I might not recover from.
You are not alone with being scared, I was and still have days where I worry. The harvest is fairly uneventful just tedious trying to lay still for so long and I was lucky enough to get most of it done in one day. The nasty bit for me was the effects from the Melphalan. I was told it would knock me for six like the previous chemo which I found was a walk in the park so thought they were just being cautious, but it really did knock me for six AND into the middle of next week!
I had very bad mucositis to the point where a morphine drip was administered for the pain. After 21 days in the Royal Marsden I was discharged with little to no energy and poor appetite, just taking a shower would leave me needing help to dry off and dress then I would need to rest for a couple of hours to recover. My energy and appetite returned slowly over the following weeks and within a couple of months I was feeling quite well. I had cinical depression too which was difficult to cope with but wore off eventually. Looking back I would say that had I been able to discuss some of my fears pre SCT with someone who had been through the same I would have coped better.
