Should I go to my doctor?

I rolled my ankle on June 5th, today's the 23rd so its been around 3 weeks? anyway, i got xrays and stuff and was told it was a severe sprain but since i was walking on it 2 weeks later my doctor assumed i was improving. i got put on 3 Tylenol 2 a day about a week ago and now my hip has been hurting for about 4 days. my doctor wanted me to see a foot specialist because he said i have flat feet and thats what caused me to roll it. i'm positive i don't have flat feet, i rolled it in high heels and on a uneven surface so i was basically doomed to roll it. should i go to the foot specialist anyway and tell him about my hip or just skip it? thanks
