<s>[INST] I hav a pain in my lower right groin when coughing or even when I do sit ups and lifting heavy things. Why is this? And 18 years ago I had an operation for hernia , I think. Could that be the reason, cause the pain is coming from the area where I was operated. [/INST] hi.. pain in the area of hernia which was operated long back due to surgeryis not common.. see your surgeon if there is recurrent hernia .. all the best.. </s>
