Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. No, it won t look like gas in the above abdomen. I suspect it is to be hernia. Abdominal content can pass through the potential weak opening. It won t requires any change in diet but it requires surgical correction. I advixebyou should visit to the nearby surgeon and diagnose the condition of direct examination. But as per your description of swelling above left and above penis, go away with pressing and gas line feeling it sounds hernia. Please avoid weight lifting until you correct it with surgery. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
