Any one heard of this? or experienced this during chemo? My mom fainted this morning due to this. She is in the hospital. The doc says its abowel infection caused due to anti biotics. She was doing fine with her chemo, apart from tiredness and fatigue and the usual numbness in her feet, which am guessing is normal. She also had severe chest pains a few days ago, which was also considered very normal. However, this infection in her bowel is a little worrying. The doctors are going to test her blood and give her some fluid through drips as she is weak and exausted. She has been eating healthy as well. I was hoping my mom would have little side effects from chemo and would get by. She just had her first session and already so many issues. Does this mean its bad? Do advice. Sorry for too many questions.
