Hi ! Good afternoon. I am Dr Shareef answering your query. Even though it needs a personal physical examination to opine on your problem, from your history alone, a developing port site hernia could not be excluded as a possibility for the cause of the pain when your intra abdominal pressure increases during any heavy work. I would suggest you to get your self assessed by your surgeon to rule this out. Till that you could go for an anti inflammatory along with a proton pump inhibitor drug for a symptomatic relief. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef.
