It turns out that Auntie Lai has been suffering from lumbar and leg pain with intermittent claudication for 7 years, and she has sought medical help from many places and taken a lot of traditional Chinese medicine which is ineffective, and the effect of painkillers is becoming less and less obvious, “this old problem is really bad to eat and sleep when it hurts”. The patient was considered to have an indication for surgery, so preoperative preparations were made. The operation went smoothly and the patient recovered well after the operation, and her back and leg pain basically disappeared the next day. Auntie Lai and her family were really happy.
