It is possible to deal with parasites on the feet without anesthesia, but if the infection is deep and the patient cannot tolerate the pain, he/she needs to inform the doctor in time so as not to interfere with the operation. Due to the harsh environment or other circumstances that may lead to parasitic infection on the feet, the parasites need to be removed through surgical procedures, and the decayed tissues as well as purulent secretions should be removed together, and finally disinfected. This procedure is associated with significant pain. If the parasites are shallow and the infection is small, and the patient has a high pain tolerance, the patient can be treated directly after sterilization. However, if the infection site is deeper, without anesthesia, it may cause the patient’s body to shake during the operation, leading to operation errors and so on. For safety reasons, it is best to be treated with anesthesia. If special circumstances can not play anesthesia, you need to communicate with the doctor in time, so as not to affect the treatment effect.
