Will my shoulder ever be 100% better? I fell last year...?!

Sooo.. I was walking through my neighborhood last summer for exercise and tripped over the sidewalk and FLEW onto the sidewalk landing on my left elbow. I thought my elbow was broken. I couldn't even move it and it was covered in blood. Well after an hour at the ER I found out it was fine, but then I soon realized it was my shoulder that was severely injured. I could not lift my arm or move my shoulder without severe pain. I finally sought physical therapy and gained better movement but it's been nearly 9 months now and I still can't fully move it like before. Will I ever regain full movement again? It's really frustrating.
