I could put my husband's name on this post!!! After his 2nd surgery and a HUGE brain infection, while on IV antibiotics, he developed a rash from head to toe. Itched constantly and could get absolutely no relief. He was miserable. Finally his infectious disease doctor determined it was from antibiotics he was taking for the brain infection. They stopped them and after steroid injections of prednisone that didn't help but the rash finally cleared up in about 3-4 weeks.
As for the fluid, he is dealing with that now, 16 months after his diagnosis and 10 months after his last treatment. ( he isn't able to take any more treatment because of kidney failure from the previous infection) We are taking a diuretic daily for the fluid and some days it isn't so bad. His ankles and left forearm swell unbelievably. No congestion heart issues, no blood clots ( had a tennis ball sized in the rt lung and several in the left), just this crazy, mean, beast called gbm. I would imagine that if we took a survey of everyone that has or is being treated for gbm right now the list of side effects wouldn't fit on the pages of this site!!! I really don't think anyone can list all that comes with this hateful monster. Everyone seems to have some of the same and then there are those that have some that others never have.
It is a rollercoaster of massive size that we as caregivers, and God bless them, the patients. I do hope that there is something can be done for you. God bless you.
Oh by the way, by my calculations we used 7 boxes of 24 pills of benadryl and 12...yes 12 LARGE tubes of benadry cream...and nothing.
