I've been on the PMR journey since 2014, and the pred episode since 2015. In that time I've also had an osteoporosis scare. Those interested in what I did about that can read healthunlocked.com/pmrgcauk... - a bit dated now, but successful anyway....
When it came to PMR I've had a lot of physiotherapy, including treatment with low intensity light therapy ( bioflexlaser.com/ ) which I think has helped me have a journey with few glitches, although in the end I don't suppose it made the process any shorter.
I found that ginger tea was helpful, seemed to help me get through the night to have a reasonably comfortable morning.
Some symptoms I was attributing to either PMR or pred (morning headaches, skippy heartbeat, gradually increasing blood pressure, very cold aching legs at nght) responded to my adding salt to my food, it appears I had a salt deficiency, almost certainly caused by eating a low sodium diet for many years.
A calcium supplement at bedtime, with a small snack (like yoghurt or kefir) cured my lifelong intermittent insomnia. I take a capsule, not a hard tablet, of either calcium hydroxyapatite or calcium citrate, others are available.
Lately, as I attempted to approach Pred Zero, it seemed to recede, like some sort of mirage. Then I read up, again, on magnesium, and started taking a small dose of magnesium. Within a day I felt well enough to step onto the path to Pred Zero again. Not going to rush, but it's beginning to feel more possible! We should be ingesting the same amount of magnesium as we do calcium, so those of us on calcium supplements need to be careful and not upset the balance between these two minerals.
What have I learned? That doctors, even sensible ones like mine, don't know very much about our condition. That many of our symptoms, whether we think they are caused by PMR, another condition, medication, simple aging, may be caused by things we tend not to think of, like a mineral or vitamin deficiency.
Don't ever take anything, a prescription or a supplement, without reading up on it, but don't believe your doctor if s/he scoffs at you if you ask about something like, for example, Vitamin K2, because they are busy people and may not be cognisant of research which is now accessible to us all thanks to the internet. And there is always the chance that something your doctor will automatically treat with another medication may turn out to be better treated through natural means. Do research whenever a new medication is suggested, Make sure you really need it. There is a place for medication (thank you pred!) but we all should try to avoid the constant piling on of more and more pharmaceuticals, some of them prescribed to deal with side effects caused by other medications.
