As a woof who became disabled at 28 from conditions that began years before as back pain; I'd say that's a legit thing to be worried about and to do the best in your power to take care of yourself now.
uh oh. can i ask what kinds of conditions, just so i can compare them to mine? currently i have a bunch of known issues with environmental allergies and joint inflammation and anxiety and muscle tension and migraines, which i've been assuming are related to the back pain. also, any tips on how to treat it?
None of my issues have much to do with allergies and muscle tension that I know of, so probably most of my experiences won't be too relevant exactly? It took me a couple years to get diagnosed with Fibromyalgia, but all the docs years later are still 'we think it's something else too, possibly EDS', but getting a clearer diagnoses has been an exhausting time of hitting brick walls.
Sadly doctors are pretty terrible when it comes to treating any sort of chronic pain that isn't an easily diagnosable form of arthritis or something (and they're even worse when medial racial, gender, age or other bias leads them to discount what a patient is saying about their pain). Most of what I know can help that doesn't deal with finding a root cause is pretty basic stuff.
Finding a chair that gives you the best possible support to be the chair at your desk you use most (you want one for you specifically, so your best bet is to try chairs out in person at a store rather than ask others with probably different needs for recommendations on what type) is probably the biggest one, especially if you're a heavy computer user. Similar with checking how well you feel supported by your mattress. Making sure you're moving as best you can can also help, trick being learning your own body's balance and not overdoing it can be pretty important too. I also find some spicy foods help a bit with inflammation related pain too? But that only works if you enjoy that sort of food.
Sorry I don't have much more useful advice than that.
