My shoulder Has hurt for about 3 years now, from 5th till now(8th) . I recollect carrying a one shoulder bag with many heavy books. My shoulder has a sharp, pressure point, burning sensation. At first at would happen every once a month, now its every day. The pain is also lasting longer now. The sensation is now causing me to use my right arm less because it cant be used for long periods of time unless rested .
Your shoulder muscles might have streched which is causing pain and burning sensation on shoulder. You should consult with therapist or chiropractor, they could help you to get rid of burning sensation on shoulder.
