Within one month of syphilis there may be symptoms such as a hard chancre and swollen lymph nodes. 1. Hard chancre: within one month of being infected with syphilis, some patients will develop a hard chancre. At first, it is mainly manifested as a single erythematous spot or papule on the external genitalia or perianal skin and mucous membrane, and with the development of the disease, it will gradually and gradually form round or oval ulcers, which are painless and have a cartilaginous hardness to the touch. 2. Enlarged lymph nodes: about 1 to 2 weeks after the appearance of the noma, the patient’s groin may show obvious enlargement of the lymph nodes, although they are usually not painful. There may not be any manifestation of syphilis within one month of infection. It is recommended that patients with high-risk behaviors who are worried about syphilis infection should consult a doctor as soon as possible for a clear diagnosis, and should not judge on their own in order to avoid delaying their condition. Do not have sex during the treatment period, so as not to lead to the spread of the disease.
