My husband has Parkinson’s and he is now 7 months out from a bone marrow transplant and the doctors where worried that his tremors may get worse once on the anti rejection meds. The Parkinson’s wasn’t effected by the chemo or anti rejection meds. He is off the anti rejection meds and the only thing he is having now is some low sodium reading for some reason and his oncology doctors are now concerned that his Parkinson meds might be causing some of this. They feel strongly that the cancer is under control so we have reached out to neurologist for their opinion on any of his meds that could cause this. One day at a time.
