Foot swelling and pain includes two aspects, the first aspect is swelling, clinically known as puffiness, the second for pain, often suggesting co-infection. Swelling of the feet is generally considered as poor blood circulation in the lower extremities due to overexertion, so it is recommended to rest, elevate the lower extremities, and apply hot compresses to promote blood circulation; the second reason is to consider the presence of phlebitis in the lower extremities, so we can consult the vascular surgery department to improve the specialist examination and pay attention to rest; the third reason is to consider the presence of rheumatic and rheumatoid diseases, so we can test rheumatoid factor, blood sedimentation and other autoimmune indicators; the fourth reason is to consider senile bone For the fourth reason, we should consider osteoporosis, improve bone density examination, and supplement calcium if necessary; for the fifth reason, we should consider the progressing gout, which is often more painful than swelling and affects rest when it is serious. If the cause of foot swelling and pain is clear, NSAIDs can be given for analgesia, especially for sterile inflammation, and early hospital consultation is recommended for more serious symptoms.
