Hi & Welcome.
I can understand your concern for your beloved husband.
He needs to be examined in ER.
Based on the history given your husband seems to have developed an incarcerated hernia in the groin (inguinal region).
An incarcerated hernia can become strangulated, which cuts off the blood flow to the tissue that's trapped and that can be life-threatening if it isn't treated.
So, take your husband to the ER for proper clinical examination.
The doctor might order an abdominal
ultrasound or
CT scan to confirm the diagnosis and if the hernia is small and isn't bothering him, the doctor might recommend watchful waiting. However, the enlarged or painful
hernias usually require surgery to relieve discomfort and prevent serious complications.
The hernia can be treated by two types of operations — open
hernia repair and laparoscopic repair.
Hope to have answered your query.
Best regards.
