Yes, unfortunately I think it is. It takes a while for bloods to recover so he may be anaemic and need a couple of units, or plasma may be low, or most likely he will be having antibiotics infused if he has a slight high temp and starting with an infection – all easily sorted and he is in the best place. After SCT I had all sorts like your dad but once at the hospital it was all soon rectified. Try not to worry as the worst bits over with just see this as a “snagging” problem. Took me about 7 weeks out of hospital to feel that I wouldn’t be having to go back in again.
