As shown in the picture, every once in a while, this position or the outer side of the foot is a bag. It's a little swollen and itchy. It'll be fine in two days! I don't know what caused it
This situation may be allergic dermatitis, so there will be such a phenomenon, but generally speaking, the impact is not particularly large. Conditioning treatment can be carried out, such as anti allergy drugs. Usually pay attention to avoid eating some spicy and stimulating things. It will be better to adhere to the treatment.
This situation also needs to see if there is any change in appearance. Sometimes rashes can also be caused. Beriberi is easy to cause. Sometimes wearing shoes is also easy to cause this phenomenon. You can bubble your feet with hot water or apply ointment appropriately.
If your feet have some redness and swelling, consider whether there is an allergy or a bag, and whether it is a mosquito bite. This is not particularly sure. You can observe it first and disinfect it with Iodophor, sometimes because of extrusion. It is also possible that this particularly itchy symptom occurs after mosquito bites.
