Hello, I have an unexpected pain on my shoulder, collar bone, hurts when I lift my shoulder. It started unexpectedly and it feels to be extending to my neck for brief moments. It also feels like those pains caused by acid reflux, but intensified x 10000 times and it feels like it radiates all over my right side.
Pain can be from many causes. What triggers or relieves it basically tells what is going on. If the pain is elicited by particular movements then it is not reflux and the particular area would tell where the pain is coming from. Usually from the attachment tendons around the shoulder joint (rotator cuff). If antacid relieves the pain that not only tells that it is indeed reflux but also shows an effective treatment.
