With the call tag of luv2run I can see why your Fev's are at 110%. I could be luv2sleep&eat which is why mine have decreased in recent years. I am 45 years old today - which is forty years beyond that which my parents were told to expect - but I'd certainly like to be in better overall heath.
So what IS the CF connection to joint pain? I see several recurring issues, but none that seem to effect all of us the same. Let's look at some:
1) Vitamin D deficiency. Vitamin D is the current "Vitamin du jour" and apparently has effects on many of our bodily systems. Vitamin D is fat soluble which means that CF patients don't absorb it well. Normal D levels in bloodwork are 30 to 100. My most recent one from early December was 11.6. Pretty low. I began on the soluble supplement Aquadeks (I had been off ADEK for about a year) and my joint pain decreased within days. Eureka! I thought. But the pain has still come and gone (as I type this my left shoulder joint is very achy) in varying severity. I'll know my current vitamin D level from last week's blood work hopefully later today.
2) Infection. When I had my first bout with joint pain in my teenage years I was regularly blowing PFTs in the 125% range. However, I DID have more sinus infections back then, which haven't been a problem in recent years.
I almost hate to say this on this site, but I've only been hospitalized for one tuneup - in 2004 - which ended up being an exacerbation due to ABPA that I probably caused when I (brilliantly) smoked some pot with my then-wife (clearly smoking of any kind is not something that I've done much of in my life, but by that point in our marriage we desperately needed SOMETHING). That 2004 time period - when I was 37 - was the most severe time of lung infection in my life. But my joints did not hurt. In fact, during the 2 hours a day when I was off IV I would leave the hospital (Albany Medical Center) and go JOGGING in nearby Washington Park. I went in with PFTs in the mid-50s, left with them in the low 80s and had them into the mid 90s within a month.
With this recent recurrence of joint pain that really hit me in September, I clearly have some low-lying infection in my lungs and am blowing in the low 80s. My Pulmonologist put me on a course of Cipro in December to "clean things out" a bit, but I don't think it did it. So perhaps systemic inflammation is playing a role at this time.
3) Medical toxicity. I have long wondered how the varied cocktails of drugs that most of us are on settle into our systems. Could this result in joint pain? Certainly. But since we're all on such a different medical regimen how would we ever figure out to what extent this is part of the joint-pain equation. One thing I can mention, for those who have seen the Cymbalta ads for arthritis pain (Cymbalta is primarily an anti-depressant) is that I have been on Cymbalta both for depression and for joint pain and it didn't help with either. I do best brain-wise on Fluoxetine (Prozac) and the only thing that really helps my pain in buffered asprin - which will eventually lead to stomach bleeding, as it did when I was a teen. Other OTC pain meds simply do not work. I LAUGH at the Aleve ads - One Aleve a day my ass!
4) Cold. My joint-pain is definitely worse when it's cold - but not just cold, cold and HUMID. But here again, when I was a teenager growing up in Colorado my joint pain hit during the summer of 1982 - a very hot and dry Colorado summer. My parents installed a hot tub later that year and the hot water always helped - but only as long as I was in it. I'd hurt again within a half hour of getting out. I have a hot tub now but with the expense of operating it and having some needed maintenance done, I'm not even bothering with it.
Lets see if we can add additional possible contributors to this list. I am printing this thread and taking it with me to my next rheumatology and pulmonology appointments. I get the feeling that my clinic doesn't even really know that joint pain is a wide-spread CF problem. My CF team never asks me about joint pain or anything like it. What about yours??
