crohn's disease
"After an infrequent 5yearly flareup of crohn's I was given infliximab intraven. for several weeks. Apparently unconnected I experienced increasing short breath which got worse and was put down to possible heart probs. Investigations were extrememely slow and I just got worse. Following almost collapse it the street I was taken to hosp and my blood oxygen levels were at 75 which is I believe extremely low and my heart was on point of collapse. Following days of being on oxygen and then a lung 'washout' under general anaesthetic and more oxygen in the intensive care dept I made a rapid recovery. Apparently I was lucky??  I was eventually told I had suffered 'acute lung damage' ie the cells that absorb oxygen. most likely from the infliximab."
