beware - doctors, private n public

hi, just want to share with all of u the recent experience i had with doctors. my wife came down with fever and was initially diagnosed by the local doctor in the area of suspected dengue. she was put on medication based on the diagnosis. after a week of off-on, on-off fever, she decided to consult a specialist in the next major town. immediately, the specialist dismissed the diagnosis of suspected dengue. she was diagnosed as having mild pneumonia with asthmatic systoms ( my wife has no history of asthma ). she was put on medication as an asthmatic patient. after a week of hospitalisation, she was discharged and given some medication to take home. the next day she felt weak and numb and trembling. this time i took her to her previous lung specialist ( not the same as the one who diagnosed her as having asthmatic problem ). the specialist immediately hospitalised my wife and after an isoscopic scan, her lungs were found to have white lining caused by the medication taken so far and there was a slight bleeding in her stomach. it was concluded that the medication given by the other specialist was too strong and the side effect was that now it has caused her to have gastric problem. so, how to trust doctors nowadays? if we can't trust doctors, who can we trust ?
