Shoulder pain and no evidence in X-ray.

Cricket player. In dec'15, my shoulder had swollen up bcz of extra effort I put suddenly on my shoulder to improve my bowling speed... Improvement was surprising for that day but on next day, I could feel the swelling and I stopped practicing... And after that I started my practice again in jan'16 and I could see the emerge growth in my bowling speed but slowly along with the time, my shoulder strength was going week... I was not being able to throw the ball very well and I could feel the noise in shoulder movements and I used to stretch my shoulders a lot. But slowly slowly my throwing ability literally came to nil as I was not being able to do quick throw even for 10m distance and then I left the field in march'17 as doctor suggested me to do so. I planned to get back to field again in dec'17 as I started to strengthen my shoulders by lifting weights since sep but met with a small accident & my shoulder started paining again but the pain is different this time and I cant throw as wel
