I was diagnosed with PMR in December 2012. My GP started me on 20mg Prednisolone and am currently on 12.5mg which seems to be working. He is a gem of a doctor who rings me on a fortnightly basis to assess the situation and at that time decides on the next dosage. I am free to ring the surgery if I feel unwell or am experiencing any side effects. He will then call me back and discuss. So far, so good., Things are going in the right direction. I have only ever experienced pain/stiffness in the shoulders and arms so am grateful for that as I understand it can also affect the pelvis, thighs etc.
