The correct one is: 病好了 which means "to recover from being ill." Let's break it down, shall we？ 病 means "to be ill" i.e. 我病了- I'm ill. 好 literally, means "good" but in this scenario, it puts more emphasis on something being complete. In this case, it means the illness is FULLY recovered. and 了 just shows a change in a situation.

1.病好了。illness has gone/ been cured. 2.病了好。病了，好！It means that you are ill is very good.It is good news for sb. sb may not do or face sth,and sb can do what sb want to do. 3.好了病。(治/让某人(sb))好了病。例：好了病(=1),我就去上班。give you another sentence:好了伤疤，忘了疼。It means that sb forgot the lesson what sb had got,and does as before when sb is facing the similar case. 4.好病了。好！病了！＝2 5.了病好。wrong,no use like this 6.了好病。wrong,no use like this

兵,means soldiers. 病,means be sick. although the two words have same pronunciation,but the meaning is different. if you want to care about sb whether he or she recovered from illness, you can ask 病好了吗？

由此三个汉字的组合可衍生出两重含义： 第一：病好了。意即病已痊愈 第二：在口语中可以做疑问句，“好了病？”，意即问他人病是否已痊愈。 你所造的句“ 好病了”则不构成任何意思，典型的病句。
