It hurts to be cold all over, especially when my heart is swollen. It's good to warm up in the quilt. How can this happen?

It may be rheumatism. When the external humidity increases and the air pressure decreases, the liquid of cells in the body will seep out. On the contrary, when the humidity decreases and the air pressure increases, the liquid stays in the tissue gap in the body. The movement of this liquid is a normal adaptive mechanism when the body cells change to the external environment.

However, in inflamed joints, the diseased tissues can't discharge fluid with the change of weather, resulting in higher pressure of local cells in inflamed joints than those in the surrounding tissues, which leads to aggravated pain and local swelling. On the other hand, in cold environment, the skin temperature of patients with arthritis drops more slowly than that of healthy people, and in warm environment, the skin temperature rises more slowly, which is due to the prolonged contraction and expansion time of blood vessels on all sides of patients with arthritis, and insufficient contraction and relaxation. Therefore, in the case of sudden weather changes, the pain of arthritis patients will be aggravated.
