I have pain in my left testicle since I woke up. Could it be due to cold? There is slight swelling.
In most cases, acute testicular pain and swelling are not caused by exposure to cold. Infection, inflammation, or more serious conditions such testicular torsion, which requires immediate medical attention, may be the cause of left testicular pain and swelling. See a doctor or emergency room right away if the pain is severe, getting worse, or accompanied by redness, fever, or nausea.
