I think that everybody is different. And I think it depends what time in our lives we get it. Also different people have different pain thresholds.
For me, it isn't progressive (at this time, who knows what will happen down the road). It has leveled off with the help of pain medications and stimulants. Without them, I don't think I would be able to function.
I admit that I had to take time off of work this winter, but I know that the cold wouldn't let me work, it was getting harder everyday. But I do plan to return in spring.
We have had some damp weather too which isn't helping things any. But it is suppose to get nice within the next couple of days.
I just take it one day at a time, if I can function, I do, but if I can't I just rest. So far, I have been productive, but who knows what tomorrow holds.
Hugs, Karen
