Causes of foot pain in the elderly include achalasia, flatfoot, diabetic foot, etc. Treatments include general treatment, physical therapy, medication and surgery. 1. Heel pain: elderly patients can wear heel pads and soft-soled shoes to relieve pain symptoms. Those with severe pain symptoms can take non-steroidal anti-inflammatory analgesics such as ibuprofen and indomethacin. If necessary, the heel can be injected into the hormone (such as prednisolone) closed treatment. If non-surgical treatment is ineffective, surgical treatment can be taken, such as the metatarsal fascia from the anterior starting point of the heel tuberosity release. 2. Flatfoot: Early physical therapy can be taken such as walking on toes, lifting the heel external rotation movement, and wearing flatfoot orthopedic shoes. Elderly patients with spastic flatfoot can be fixed under anesthesia with manipulation and plaster inversion. 3. Diabetic foot: first of all, blood sugar should be controlled. If the diabetic foot has a simple ulcer, you can change the pressure of the foot through conservative treatment (such as wearing special orthopedic shoes), clean the wound and change the medicine. For those who cannot be controlled by conservative treatment, surgical treatment is feasible. In addition to the above reasons, foot and ankle trauma, such as ligament strains, can also cause foot pain in patients. In addition, elderly people who suffer from foot soft tissue sprains and tears or fractures due to trauma may also experience the above symptoms. If the above symptoms are not relieved, it is recommended to go to the hospital to find out the cause of the disease and under the guidance of the doctor to carry out regular treatment. The above medications should be used in accordance with medical advice.
