The BSR guidelines for PMR and GCA are currently up for review and updating, and an international group is also working on a project to establish a set of globally shared guidelines for PMR. However, it's a while since we pointed you in the direction of the guidelines that are currently in operation. These are written for the benefit not only of rheumies but also GPs. We don't think they are perfect, a) because knowledge is partial and b) because these conditions vary so much from person to person. But they are a good place to start if you need to get more knowledge before discussing your condition and treatment with a doctor.
Take care of yourselves!
