Hi Pandemonium!
Sorry to have to welcome you to our club! And heavens - I'd hate to be a teacher with this!
Anyhow - if you have been diagnosed with PMR and started on 10mg pred you need to go the northeast pmr-gcauk support site (google that lot to get a link, if I put it in this post it will disappear for ages while they moderate it and still probably won't leave it in!). There, on the right side of the screen, you will find a heading something like \"useful information\" which will lead you to the British Association of Rheumatologists Guidelines for diagnosis and treatment of PMR. Download it and take it to your doctor. There is also an article about steroids - what they do and how to take them and another about living with PMR. The info all comes either from rheumatologists experienced in dealing with and researching in PMR or from patients who have been living with it for a while. It can be trusted.
The reason I say this is because there is no way 10mg is enough at the start for PMR - you start on 15mg and may need to go up a bit if the response isn't good enough. The PMR symptoms should respond dramatically to that dose - they may not disappear altogether but should improve by 50-70% within a few days. If they don't then the diagnosis of PMR needs to be questioned.
Once the inflammation has been controlled with that dose - which is usually allowed a few weeks or so at least, maybe longer - you can start to drop the dose. I found a reference last week where they said that any single drop should never be more than 10% of the current dose. Normally you would look at dropping from one dose to the next and staying on that for at least a few weeks before trying to drop again. The aim is to get to the lowest dose that controls the inflammation and - as a result - the symptoms which make life so difficult. So to get from 15 to 10 should take a couple of months at least - and if the symptoms return, then you should go back to the last dose at which you were comfortable, wait a bit and try again. If you are in pain/stiff etc - you are at too low a dose.
Let me emphasise - you may know this already of you have read a lot of this forum - steroids DO NOT CURE PMR. There is no cure as yet, nor one on the horizon. It is a question of controlling the disease to allow a decent quality of life. There is no point at all of taking steroids at too low a dose to do that. Many doctors, especially GPs, seem scared of steroids and will try to get you off them asasp. In that case - why start them in the first place? I won't deny the fact that steroids are not sweeties - they are powerful drugs and need to be treated with respect. However - they are no way as bad as they are painted by many people and if the alternative is to have to sit at home, in pain and depressed, unable to work or even have a decent retirement - what's the point of saying that steroids are dangerous? You MIGHT develop osteoporosis, you might become diabetic, you might put on weight, you might suffer other side-effects - you might not. Until you take them you don't know which side-effects will appear.
I have been on steroids for about 16 months - I put on weight before diagnosis because of 5 years of restricted activity because it wasn't recognised followed by 6 months of really bad symptoms until someone agreed with me PMR was a possibility. I haven't put much more on and at present I think the abdominal fat is going slowly. My BP is fine, I show no signs of diabetes, my skin is fine. I can live a nearly normal life - before steroids I couldn't walk far, I couldn't even do my ironing for more than 15 mins at a time and I was in constant pain. There were loads of things that were impossible. I'll take the risks of steroids.
One other warning (for want of a better term) - the steroids won't necessarily do much about the fatigue. That is part of an autoimmune disease and, although it should improve, it will be there in the background and if yo
