If there is a throbbing below the raphe, it is necessary to actively improve the examination to clarify whether there is an aortic aneurysm in the chest and abdomen, which is a very critical condition. If this disease is excluded, generally speaking, there is no big problem, it may be a long time in one position resulting in localized compression caused by muscle spasm. Localized muscle spasm can lead to muscle twitching, causing involuntary throbbing under the xiphoid process. Positive attention to rest, avoid local compression, local hot compresses can be relieved by themselves.
