If you have pain in the hip joint and want to relieve the pain by applying a plaster, you need to clarify the cause first. If inflammation of the hip joint causes pain, it often manifests as pressure pain on the anterior side of the hip joint. Depending on the location of the pain, most of the plasters are applied to the anterior side of the hip joint, which is the location of the groin. In clinical pain of the hip, the painful area is located at the greater trochanter of the femur, and there will be obvious pressure pain at the greater trochanter of the femur, so you can put plaster at the greater trochanter of the femur.
