Achalasia, also known as heel pain, is a common condition in foot and ankle surgery, especially in middle-aged and elderly people. The disease usually starts slowly and has a long course. In mild cases, heel pain can occur when walking, and in severe cases, it can even affect the normal activities of the foot. In the past, heel pain was thought to be caused by heel spurs, but according to clinical observation, about half of the patients with heel pain do not have bone spurs in the heel. In fact, it is often caused by metatarsal tendinitis, heel spurs, heel fat pad inflammation, heel subacromial bursitis, plantar nerve entrapment, Achilles tendinitis, Achilles bursitis, heel hypertension, and heel stress fracture. The elderly due to the gradual aging of the soft tissues of the foot, tissue elasticity and function is declining, it is easy to strain, therefore, the elderly usually pay attention to take good care of their feet, avoid standing for a long time, often use hot water to soak feet, the conditions can also be regular foot massage. Once you have heel pain, patients should not worry. Generally speaking, with proper treatment, most patients with achalasia can get relief from their symptoms. Michelsson et al. proposed a three-model, four-stage approach to the treatment of achalasia. In addition to patient education, conservative treatment is divided into three modes according to the mode of action: 1. relief of pain and elimination of inflammation (anti-inflammatory and analgesic treatment); 2. reduction of soft tissue stress (rest and application of various orthopedic appliances); 3. maintenance of soft tissue contractile elasticity (various exercise and physical therapy measures). The three models were applied to the four phases of treatment according to the patient’s symptoms, condition and response to treatment. Stage 1: The patient has been onset for several weeks and has mild symptoms. The main treatment methods include rest, cold compresses, wearing appropriate shoes and insoles, non-steroidal anti-inflammatory drugs for 1 to 2 weeks, and 10 minutes of muscle pulling exercises completed in 2 to 3 sessions per day. Stage 2: The patient’s symptoms are severe and last for several months. The main treatment methods include night splint application for 4-6 weeks, especially for patients with morning walking pain, the earlier the night splint and exercise, the better the results. Local closure: 1 ml of methylprednisolone (40 mg/ml), preferably with an appropriate amount of local anesthetic for better results. Non-steroidal anti-inflammatory drugs can be used as an adjunctive treatment in the above cases for a course of 10-14 days, which can last for several months. Phase III: Before surgical treatment. The main treatment methods are: extracorporeal shock wave and plaster fixation. Shockwave is safe, without complications, and although the results are reported to be inconsistent, it is still a treatment option for patients before surgery; plaster fixation is mainly to force patients to rest and temporarily relieve symptoms. Stage 4: If the symptoms are not relieved or worsened after at least 1 year of conservative treatment, surgical treatment should be performed. Achalasia can be caused by a variety of diseases with complex etiology, and sometimes several factors coexist. Therefore, a clear diagnosis should be made first, so that treatment can be targeted. In most cases, conservative treatment can achieve satisfactory results, and conservative treatment can be combined with several treatment methods according to different etiologies. For the few patients who need surgery, we should strictly grasp the indications for surgery, carefully investigate during surgery, and choose the appropriate surgical plan according to the etiology.
