I have been suffering from ac joint separation in my left shoulder for the past 3 months I've tried resting the shoulder many times yet there's no change There's no pain or discomfort although my range of shoulder motion is affected slightly, Visual Symptoms - a slight bump on the shoulder joint indicating the separation. I remember 1st locating this due to my improper bed rest positions during night.  I am unable to do pull ups, I am unable to perform proper shoulder raise workouts - left arm only I am.feeling a knuckle sound when I'm benching and performing chest and shoulder workouts Is there an appropriate home solution for this?, other than ice packs(since I have no swelling or pain) Quick responses would be highly appreciated :) Thank you
