Hi,
Welcome to health care magic,
Due to your inguinal hernia, you need to go for a lighter work where there is no lifting of heavy weight leading to increased intra-abdominal pressure.
The present status of your hernia seems to be well advanced. It looks like getting irreducible and obstructed at times giving rise to the acute pain and distension like symptoms.
If I were your doctor, I would advise you for an elective but urgent surgery for your hernia to prevent any further debilitating complications like a strangulation, and also to make you fit for your work early.
Till the surgery is scheduled, you have to get yourself assessed by the team of doctors for pre
anesthetic fitness. I would also advise you for a good scrotal support and an abdominal binder in the lower abdomen (or a truss) to prevent the hernia from coming out frequently till the surgery is done.
Truss is an old way of treating conservatively the inguinal
hernias which is not very popular now a days.
I hope this information would help you in discussing with your family physician/treating doctor in further management of your hernia.
Wishing you an early recovery.
Regards,
