My 15 year old daughter underwent surgery at CHOP on April 23. She was discharged 2 days later with the usual discomfort. We were warned that by day 7-10 she could develop chemical meningitis. She now has excruciating headaches and nauseau. The surgeon said to "stay the course" and this is very uncomfortable. It is so difficult to see her suffer like this. Does anyone on the forum have a (happy) story to tell me about their experience with CM?
