Since being diagnosed with PMR 4 months ago I have been reducing my dosage of Prednisolone from 30mg to 15mg. Over the last month I have had daily headaches which my GP has put down to stiff neck muscles and prescribed Amitriptyline. This has not provided relief and I am now waking up each day with severe aching on the right side of my head. It starts at about 4.30 each morning and gradually goes during the day. I am reluctant to go back to my GP as I'm beginning to feel a bit of a hypocondriac but having returned gradually to work, this pain is dragging me down again. Could it be GCA?
