I injured my left shoulder about a year ago and have never fully recovered. I hurt my nack while moving the lawn, and the pain has persisted for over a year. So I have been taking Panadol for this. The pain travels up my neck and across my clavicle to the base of my skull. It could be throbbing or stabbing. I can not lift my left arm above my head, and my strength in that arm is not what it used to be. It sometimes makes me panic, and I have heart problems. I work long hours and have not been to the doctor because they are closed when I get off work. Please help.
