When it rains or catches cold, my knees and ankles are very painful. Is it rheumatism?

Arthritis, right? Or rheumatoid arthritis

Why are arthritis patients particularly sensitive to the weather? It turns out that before the arrival of major weather changes, there will generally be a significant drop in air pressure and a sharp rise in air humidity. In normal people, when the humidity increases and the air pressure decreases, the liquid in the cells will ooze out, while when the humidity decreases and the air pressure increases, the liquid will stay in the interstitial space in the body. Normal people can hardly feel the change of the weather, while arthritis patients can't discharge liquid in time with the change of the weather, which leads to the cell pressure of the lesion higher than that of the surrounding normal tissues, thus causing the swelling and pain of the lesion. This is the secret that arthritis patients can predict weather changes.
