Persistent pain after calcaneous surgery

About 4 months back I fell off a wall and landed on my foot and broke my calcaneous(heel), I was admitted in hosmat hospital in Bangalore and undergone a surgery with 3 K-wires at the back of my heel and in cast for nearly 6 weeks. Then the K-wires were removed and I was in walking cast for next 6 weeks. After checking my x-ray doctor asked me to get rid of the walker and get back to regular work. My biggest problem is that I have this persisting pain, around the subtalar joint area and my walking has changed(I have a limp). Will this pain reduce over time,? I am doing my PT. How long does it take to get to normal state(I want to get back to running, can't imagine a life without playing football).
