Quite a lot of people with joint pain will indeed report that their problem gets worse in certain climatic conditions, although often they say this as if they don’t expect anyone to believe them. I don’t know if this is because certain experts poo-poo such claims, or because the patients themselves, not knowing about Dr Hollander for instance, think it sounds unscientific to suggest such a connection. I suspect it is more because it is information which is not useful for a GP or even a rheumatologist, so that if the patient tells them their condition gets worse in the damp, for instance, they just grunt noncommittally.
When we treat joint pain (or any other condition) with TCM, however, we are decidedly interested in whether the weather affects it, and that is because it will influence our choice of treatment. For instance, in the classic case of someone who has knee pain which seems to be worse in cold and/or damp weather, we will almost always supplement our acupuncture treatment with either moxibustion, or with a TDP heat lamp. Moxibustion involves applying heat to the local area by burning moxa, the herb mugwort, perhaps on the end of the needles; the Chinese, indeed, have used moxa in this way on arthritic joints for millenia.
Therefore, at least from our point of view, it is really important to notice how the weather affects you, and if you do feel ‘under the weather’, then be aware of what the weather actually is!
