A possible way to correct the sentences by eliminating their respective dangling modifiers is the following:
A dangling modifier happens when a word, phrase, or clause describes something or someone, but it is not clear to what or whom they refer. That creates ambiguity in the sentence, that is, it allows for more than one interpretation.
Let's take sentence 1 as an example. The dangling modifier is "unable to bear the pain." It is not clear if it is the doctor or the speaker of the sentence who was unable to bear the pain.
We can assume it was the speaker because it is usually the patient who suffers from an issue. With that in mind, we can change the sentence to make it clear that it was the speaker who couldn't bear the pain.
