The guidelines now say "over 50", they used to say "over 55" but there are people in their 40s that we know of with definite PMR (inasmuch as that can be said - typical clinical symptoms that responded dramatically to pred) and the youngest patient in the medical papers was 26! It's more the majority of people are well over 50, the average age at diagnosis is 73 and half of 80 year olds will have it and that makes the average higher.Personally, I suspect there are a lot more out there who are under 55 but PMR wasn't considered as a diagnosis but they were fobbed of with "it's your age", "fibromyalgia" or "all in your mind" and we've got quite a few who've experienced that last attitude from male doctors.
However - since your doctor did no blood tests and didn't try pred it COULD be something else and he needs to have a few checks. PMR is what is called a "diagnosis of exclusion" - that means you rule out the things that can cause similar symptoms and CAN be tested for in various ways. Then, with a suitable clinical picture and a dramatic response of improvement in the symptoms of about 70% to 15mg/day pred within a couple of days, he can say "PMR".
Something else that they should also look at is your hormones - something very similar to PMR can be found in relation to the changing hormones at the menopause. There is a thread on this forum somewhere from a lady for whom HRT made a dramatic difference after pred didn't do a lot - she was lucky, the practice nurse saw what pain she was in getting onto the couch for a smear and after some questions told her which doctor to see (a lady who knew about it).
If it is PMR you won't necessarily be pain-free on pred either - it is a chronic form of rheumatism that requires some lifestyle changes too but pred makes a big difference and allows a fairly decent life for the majority. Most of us are retired, I work but not standing or other heavy stuff - sitting at the computer was bad enough sometimes until I was given pred (after 5 years). Since then it has been walking that has been the bugbear but that is improving now after a difficult year with other problems as well last year.
I can't remember - did I give you the reference for the Kirwan paper which is aimed at GPs who do struggle with diagnosis and management of PMR? I've looked now and the answer to that is no ;-) but if I give you the link this post will disappear. So here is the title of the paper:
Our approach to the diagnosis and treatment of polymyalgia rheumatica and giant cell (temporal) arteritis by V Quick and JR Kirwan
When I copied and pasted that into google it came up as the second "find" (with rcpe in the ref) - click on that and it will load so you can read it or print it off. It isn't particularly difficult to read the majority (sorry if I sound patronising but I have no idea what your background is in the hospital). You don't need to worry about the statistics (makes me yawn too) but there is quite an impressive graph which shows how symptoms improve dramatically after you are given 15mg pred and come back the same when it is stopped after a week if it is simple PMR, improve a little bit if it is a couple of other things and the pred has no effect at all in yet others. It also gives their "tried and tested" reduction scheme as information for GPs faced with such patients.
It is aimed at GPs, as it says at the beginning. I would print it off and offer it to your GP. Kirwan maintains that giving a week of vit C, a week of 15mg pred and then another week of vit C will distinguish most cases of simple PMR. Why vit C I have no idea unless they have tablets that look similar so the patients don't know what is what - the improvement in symptoms must happen within 48 hours or so of starting pred. If it is psychosomatic (in the mind) there might be an improvement with the vit C - just because they are being treated with something. It is a diagnostic approach any GP can try without sending their patient to hospital to a rheumatologist.
The state you are in at the moment can't go on - you will simply end up having no life at all. Life that is all work and pain is not worth having - and one of the other aspects of PMR is depressive mood: it can be part of PMR anyway, chronic pain will lead to depression too as I'm sure you know.
When I started on pred I took the first dose at just after 10am after picking them up from the chemist - much later in the day than you should really - and at about 4pm I got up from the computer and walked downstairs normally and with hardly any stiffness for the first time for months instead of like a toddler, one step at a time hanging onto the handrail. It can be that dramatic - it didn't remove all the pain, I had tendonitis and bursitis too and that took several months to near enough disappear, but it did get to a livable-with state quite quickly.
Do let us know how you get on - if your GP is difficult, try another one who will listen. They can manage you themselves on the basis of that paper without sending you to hospital if the "check" using pred is clear. Otherwise they need to look for something else. Either way, you need something concrete to be done.
