Tendon sheath inflammation refers to chronic aseptic inflammation caused by excessive and frequent flexing and extending motions during labor, where the tendon is subjected to repeated friction and compression within the fibrous tunnel of the tendon sheath. This results in local exudation, swelling, and fibrosis, leading to a narrowing of the sheath canal and hindering normal tendon movements. For mild symptoms of tendon sheath inflammation, treatment can include rest, immobilization, physical therapy, and topical non-steroidal anti-inflammatory and analgesic medications, as well as anti-inflammatory and pain-relieving plasters. If symptoms do not improve, local injection therapy may be employed. If symptoms persist and conservative treatment is ineffective, surgical removal of the narrowed tendon sheath may be necessary. (Please use medications under the guidance of a doctor.)
