Hi again, - thanks for your post and question. As I recall, we have had previous conversations here in our community. As best as I can tell, some go back to 2021, and are also related to back pain. Should you be interested in reviewing any of the content, here is a link for your convenience: https://copd.net/moderation/users/2454337.
As far as your comment from earlier today, sometimes it can be difficult to determine which illness is responsible for which symptom. That is part of the challenge of being a physician/diagnostician, right!?
It's understandable that with COPD, atrial fibrillation, and arthritis, you might be feeling fatigued on a fairly regular basis. Each disease/condition, in its own way, can cause a certain level of fatigue.
To answer your question whether COPD causes back pain - the answer will depend on the patient, the disease and, how the disease affects each individual patient. We actually have a wealth of material, published right here on COPD.net, which focuses on that very topic. For your convenience, here is a link to several of those articles: https://copd.net/search?s=COPD%20back%20pain. I do hope you find the information is helpful in a practical way.
If there is anything more about this topic (or any other), that we can assist you with, please let me or any other moderator / team member know.
Wishing you well,
Leon (site moderator COPD.net)
