since引导从句,主句完成时,从句过去时,主句是现在完成进行时,你们刚接触这个时态吧,还有Been是be的过去分词,所以用feeling,明白了吗?希望对你有用,手机码字不容易,正在冲采纳率,望采纳!谢谢!

这是一条语法规则，since引导的从句中，主句用过去完成时，而从句用一般过去时。所以后面是 the doctor came ，而不是 the doctor has came。
另外根据句意，是指现在感觉良好，所以用了进行时。

你记住，一般since从句用过去时，主句用完成时。医生来了，动作发生在过去，我感觉好多了，并不是过去感觉好多了现在就不好了，而是到现在为止感觉好多了（对现在有影响，用完成时）
P.S.你的feeling拼错了

I am not felling very well. I__have__to see the doctor.
我感觉很不好，我必须去看医生！
have to 必须
