Talk to Orthopedic Surgeon on Shoulder Pain

I fell from bike about almost 3 years ago on my left shoulder side, at that time I didn't feel any pain. But after that I feel pain occasionially and it goes away by itself. I also do exercises and it doesn't feel any pain but for some reason it comes back for a few days and then goes away by itself. Now currently the pain is in my shoulder blade, previously it was in front delt. I have consulted with few doctors, they gave some medicine and physiotherapy advice (I don't remember the medicine's name) but it didn't have any affect. For the physiotherapy part, I was doing exercises and I told the doctors and they said it was fine. But I don't understand why it is not healing properly. And why the pain has migrated to shoulder blade also. I came here because I was told that I might find some competent doctors here, because the doctors I showed myself to weren't competent at all.
