The more common cause of foot pain is plantar fasciitis. For example, if you sleep at night and get up the next morning, the pain will be especially obvious, and the pain will be gradually relieved after appropriate activities, you should consider plantar fasciitis. After this symptom occurs, it is recommended to stand or walk as little as possible, and to soak your feet in hot water bags or warm water before going to bed at night. When sleeping, try to elevate both lower limbs and wear soft-soled shoes in daily life to relieve the pain of plantar fasciitis. There is also the sudden appearance of pain in the toes after waking up from a nap, mostly considered to be caused by gout, often with food such as beef, mutton and seafood the day before going to bed. If this situation occurs, it is recommended to go to the hospital to check the uric acid to see if the uric acid is high, and then treat the symptoms.
