Heel pain is a common clinical symptom in middle-aged and elderly people. Chinese medicine considers the deficiency of kidney yang to be an important factor in causing the disease. Heel pain is a comprehensive set of symptoms caused by lesions in different tissues around the heel bone. Etiology】 With age, human tissues undergo degenerative changes and long-term strain causes pathological changes in the heel tissue. Such as heel fatty fibrous pad inflammation, metatarsal tendinitis, heel bursitis, Achilles tendon periarthritis, heel hypertension and heel bone spur, etc.. These corresponding diseases in different tissues around the heel bone are the important causes of heel pain. [Clinical manifestations and diagnosis] 1. heel fatty cushion inflammation heel fatty cushion is referred to as heel cushion, which is separated by elastic fibers and consists of encapsulated fatty tissue, which has the effect of absorbing shock and preventing sliding. Heel stabbed by hard objects or long-term compression or wind, cold and damp invasion caused by heel pad inflammation. The patient has pain and swelling under the heel with superficial pressure pain. The medial pressure pain in the weight-bearing area of the heel, the atrophy and thinning of the heel pad in the elderly, easily cause symptoms, local fibrous masses can be palpated; 2. Metatarsal tendonitis metatarsal tendon membrane from the heel node and to the metatarsal bone, is the larger elastic tendon membrane of the sole of the foot. Trauma, strain and cold and humidity can cause inflammation of the metatarsal tendon membrane, and those with valgus foot are especially prone to this disease. Patients often have pain under the heel or the heart of the foot, a sense of pulling and tension on the bottom of the foot, and significant pressure pain in the heel node area and the middle part of the tendon membrane; 3. Heel bursitis Trauma or repeated friction can cause inflammation of the bursa under the heel, after or before the Achilles tendon. Patients have local pain, swelling, and pressure pain. If combined with infection, it can cause typical inflammatory manifestations such as redness, swelling, heat, and pain; 4. Achilles tendon periarthritis: inflammation of the tissues around the Achilles tendon attachment site due to trauma or strain causes swelling and pain in the Achilles tendon. The patient’s Achilles tendon becomes thicker, with localized pressure pain and frictional sensation, and axial strangulation sounds may appear when the inflammation spreads to the tendon sheath. The pain can be aggravated by dorsiflexion and plantar flexion of the ankle joint. Achilles tendon periarthritis is often due to wearing hard heel, hard shoes, long-term pressure friction formation; 5. Achilles hypertension heel bone itself due to chronic compression or bone degeneration, the heel bone internal pressure increases resulting in heel pain. Achilles hypertension is mostly seen in middle-aged and elderly people, and can develop unilaterally or bilaterally, with pain in the heel affecting walking. Early elevation of the lower extremity can relieve the symptoms, and there is pressure and percussion pain on the medial, lateral and metatarsal sides of the heel. The heel bone spur is effective for decompression therapy; 6. The repeated pulling injury of the metatarsal tendon membrane and the toe flexor or Achilles tendon, degenerative changes of the heel bone, and the cone-shaped bone formed at the heel attachment site of the metatarsal tendon membrane is called bone spur. The direction of the bone spur is mostly consistent with the direction of the Achilles tendon and the metatarsal fascia. The heel spur can be clearly seen on lateral radiographs of the heel bone. However, patients with heel spurs do not necessarily develop heel pain. When heel pain is present, the heel spur is often present after treatment has resolved the inflammation in the soft tissues surrounding the heel bone. The heel spur is a characteristic manifestation of degeneration and aging of the bones and joints of the elderly. Treatment】 The onset of this disease varies, but heel pain is its common feature. The pathological changes are inflammatory changes in the soft tissues surrounding the heel and increased intraosseous pressure in the heel bone. Treatment mainly uses acupuncture, massage, physiotherapy, external blood circulation drugs, hydrocortisone acetate 25mg plus 1% procaine 2ml or hydrogenated prednisone acetate plus lidocaine 2Tnl painful point local seal, so that the local sterile inflammation subsides. Fibrofatty pad inflammation of the heel can be treated with soft insoles hollowed out in the middle of the heel. Surgical excision may be considered for bursitis that is persistent. If conservative treatment of the heel spur under the oblique front is ineffective, surgical excision can be performed, and the muscle attachment point can be relocated, and the heel nerve can be severed in cases of persistent pain. In cases of intraheel hypertension, decompression of the medial and lateral heel spurs is possible to eliminate the symptoms. Heel fracture, fracture deformity healing, heel tuberculosis, osteomyelitis, gout, tumor and metatarsal tunnel syndrome can cause heel pain, which should be differentiated from the above diseases.
