I am five weeks post transplant. I am a 45 year old male who, aside from having MM, is in good health. I have IgD non-secreting. Here is my experience.
I was in the clinic for a total of 12 days. (The hospital keeps many transplant patients in an apartment with a caregiver rather than admitting them to the hospital.) The melphalen injection took about an hour. I chewed on ice the whole time and had no trouble with mouth sores in the subsequent weeks. I also used the rinse they gave me at least four times a day even though it tasted like marsh water. The next day I received my stem cells.
The worst side effect I felt was fatigue. I slept a whole lot. I also experienced a weird sense of smell and taste. I went home on day plus 10 because the stem cells started to graft. However, I was extremely tired the first week. I took naps every day. On the third week after I was discharged I returned to work, although I was probably at 3/4 strength. Now, at five weeks post-transplant, I sleep a normal amount (seven to eight hours) two out of three nights. I find that on the third night I need about 10 hours of sleep.
I will be restaged later this month. I may have another stem cell transplant in January. I do not know if it will be an auto or an allo.
