The symptoms of redness, swelling and pain in the big toe may be due to nail fungus. Patients with nail fungus can experience redness, swelling, heat and pain due to a bacterial infection in the toe. In addition, patients suffering from gout can also experience painful toe symptoms. Gout is a very common bone and joint disease that is generally caused by abnormal purine metabolism. If the patient normally eats foods with high purine content, it can cause an increase in uric acid and cause gout, which can result in sudden pain in the toe joints with redness and swelling. In this case, it is recommended to check X-rays, blood routine, blood sedimentation and blood uric acid at the hospital. If it is caused by bacterial infection, antibiotic anti-infection treatment needs to be applied. If the pain in the toe is caused by gout, then you need to apply uric acid-lowering drugs for treatment, and in addition, you need to apply anti-inflammatory and analgesic drugs to relieve the symptoms of pain. Patients with gout should be careful not to eat foods with high purine content, such as seafood, spinach, etc., and not to drink alcohol.
