I recently began having a burning sensation in my left shoulder blade. It feels like someone has put Ben-Gay on it. For several weeks this sensation occured daily. No pain accompanied. Lately, however, pain does accompany the burning. Each day the pain gets a little worse. The burning lasts only a few minutes, the pain lingers for a while. Movement is not limited. It happens only on the left side. There is a lot of repetitive movement in my job, and the possibility of poor ergonomics has entered my mind. However, my co-workers lift, twist, pull the same way I do, and they have not experienced this. Also, it happens daily, including when I have been off for several consecutive days. My husband was injured at work a few weeks ago, and is waiting for MRI results and probable surgery. Because of this, he has been home from work since the injury, therefore making an appointment for myself at this point is not a financial option. My symptoms are managable at this point, but would like some ideas of what could be the cause, and if it is something that I should have checked when I am able.
