When a patient has joint pain after blowing on the air conditioner, it is usually due to the erosion of the joints by cold wind, which leads to spasm and edema of the synovial membrane inside the joints, thus causing significant soreness and pain in the joints, and when the surrounding ligaments and joint capsule are stimulated by cold wind, it also tends to lead to spasm and contraction, and this will aggravate the pain in the joints. In addition, when the cold is severe, it is easy to increase the fluid exuded from the synovial membrane, which causes fluid accumulation in the joint, swelling and pain in the joint. Therefore, in this case, you must pay more attention to keep warm, avoid getting cold, and apply more heat to the joints to relieve the joint pain caused by blowing air conditioners.
