I fall from riding bike on right arm then left arm sliding about 5 metres later I couldn't lift right arm even half of shoulder height as there is pain in shoulder I also did xray but it was ok and doctor said it is muscle problem you have to go to physio when I go to physio he said to take rest for a weak later I can lift half of shoulder height easily but not fully to shoulder height as now it has been 15 days but problem is there.
