Last chemo treatment put me in hospital

Had a very positive oncology consult which was to review the PET scan done 2 days earlier. While he couldn’t access it yet, my bloodwork revealed extremely good numbers including near normal cancer markers. So good, he said he fully expected a good PET scan report. Off I go to treatment upped to 80% oxaliplatin from 50%. Fine. Woke that evening extremely ill and out of it with asthma symptoms also. Wound up at the ER next day but never left. My BP was so low they considered putting me in the ICU and had potent meds to bring mean arterial pressure up. Now it’s day 4 - broad band IV antibiotics due to fever, in isolation-telemetry room , x-rays, cat scans, cultures, nebulizer treatments. All the time feeling sicker than any time of my life. Began coughing sputum with blood flecks which could be from severe irritation of windpipe.
Bottom line hypothesis is an acute chemo reaction with infection somewhere that is now under control. Stearoid and breathing treatments are starting to help the asthma like symptoms and I’ve had first bite of food in 4 days plus on the enteric pump.
I believe I’ve turned a corner and will go home tomorrow or Monday.

I guess they might have to modify my chemo formula to avoid such a terrible reaction in future rounds.
