Sciatic node cysts are a less serious clinical condition. Because the muscle soft tissue at the sciatic tuberosity is less covered and located under the skin, so especially for the elderly patients or patients with thin body type, the sciatic tuberosity is more prominent, and the soft tissue covered by its surface is more reduced, if long-term bed rest or sedentary, it is easy to cause cysts at the sciatic tuberosity. Symptomatic treatment, in general, can be taken non-surgical treatment, can achieve satisfactory therapeutic effect, such as changing bad habits, avoid sitting for a long time, avoid long time lying down, can be changed to the side of the way, can avoid the sciatic node long-term pressure load. If the pain is obvious, local non-steroidal anti-inflammatory drugs can be given, such as fenpropidone and fuselin tablets, etc. These drugs can reduce the aseptic inflammation locally and achieve the effect of reducing the cyst.
