I agree with you that 病人自己點藥 is not good. I guess I was just lucky that it worked this time. At least this time 對病人(沒)有好處. In fact, I trust my PCP very much and that's why I went back to him again and again (visited him 3 times). He simply did not help my condition at all. I didn't see any alternatives. For me at that time, the potential benefits of taking antibiotics way way outweigh the potential costs. I was taking extra strength Teynol for the pain. All he did was saying it would go away.
