Question maybe someone can help me

Am

Health related I may not get any help here. Two weeks ago I fell down stairs on my side and tried keeping myself from rolling on my stomach by keeping my arm on the hand rail. and for about 4-5 days I couldn't move my arm above my shoulder. Well right after that my shoulder started feeling a "disconnect" feeling from my body and it hurts. Especially when relaxed. It feels super heavy and I'm constantly uncomfortable. When I go to move my arm i feel like I have to help my arm get moving and kinda lift it back into place. It get weak and sore much fast than my other arm and it's my dominant side that's hurt so it's weird to begin with. I know I need to see the doctor but how will they be able to tell since x rays are so risky?. 😭
