Context: I skipped the anti - inflammatory , because honestly , I really do n't like taking any of these drugs . But , I will say that this other medicine seems incredible . Granted , the swelling had already gone way down by the time I took it but within hours , my foot seemed better . Yesterday , after dropping Mr. David off at class , I went over to Target and WALKED for over an hour . I had no problem going around campus , although I am not walking as fast as I am used to . This morning the swelling is gone , although I can feel the sesamoid digging in again , which means it 's slipped out of place again .

Question: What might have happened before I received my medicine ?
Options:
0. I walked for over an hour at Mr. David 's class .
1. I sprained my ankle before going to the doctor 's .
2. I dropped off Mr. David at Target and walked for an hour .
3. I sprained my ankle after going to the doctor 's .
Answer: 1
