Caudal spine pain after prolonged sitting is mainly due to prolonged sitting, resulting in muscle strain and inflammation of the sacrococcygeal muscles, which in turn leads to pain. This is typical of myofascial inflammation, which is characterized by localized tingling and swelling pain and can induce severe pain when pressed or touched by hand, but can be more comfortable when tapped by hand. The correct treatment should be to ensure adequate rest, avoid prolonged sitting, or if you must sit, put soft cushions on the stool to reduce local friction or stress, and give hot compress treatment around the pain. If the pain is severe, medication can also be given, mainly non-steroidal anti-inflammatory and analgesic drugs, together with muscle relaxants, dehydration and swelling drugs, commonly used drugs are Cilabao capsules, anti-depressant tablets, Eperisone capsules and so on.
