Enlarged and red testicles after a recent varicocele surgery can be normal. If the redness of the enlarged testicle lasts for a long time, it may be due to the presence of infection. When the varicocele is more serious, surgery is usually needed. During the surgery, due to the damage to the local blood vessels, there may be pain, swelling and redness in the initial period after the surgery. Therefore, it is normal for the testicles to appear enlarged and red when the varicocele surgery has just been performed, as long as it is not particularly serious. After varicocele surgery, if the symptoms of redness and enlargement of testicle last for a long time and there is oozing, you should be alerted to postoperative infection. After diagnosis, you should apply anti-infective drugs for treatment, such as azithromycin, levofloxacin, etc., to control the infection in time to avoid affecting the recovery. If there is any abnormality or discomfort after surgery, timely follow-up is recommended. When using medication, be sure to follow the doctor’s instructions, safe and reasonable use of drugs, do not use drugs indiscriminately.
