Pain due to retrocalcaneal spur. Cups.

I am from Kharghar and have got severe pain near bursa in my left foot. Last time an Orthopaedic told me it's retrocalcaneal bursitis but later on another doc told me that I have calcaneal spur in both feet, on both down side and back side. I had pain in my lower heel spur for few years which now has subsided on its own. But from last 3 months, I have this pain in back side of my left foot (bursa side), for which I have attached the x-rays as well. For your info, I met an accident (fell from height) in Dec 2016 and got my tibia fractured, for which there is a plate fixed. My recovery was going fine but now I am not able to do anything from last 3 months. I have got physiotherapy done, therapeutic ultrasound and TENS done, ice pack, contrast bath, everything what my doc and physio has asked to do, but all in vain. Please advice. I wear one size larger shoe to keep my foot comfortable, with normal heel. I have not yet wore insoles or heel cups.
