<s>[INST] I have bloating , tenderness in the lower right quadrant. I went to the ER center, where I had blood and urine test done. I don t have a fever. The results show no infection and no sign of appendicitis . The doctors checked for hernia and failed to locate one. This has been going on for 2 months. I am 29 years old male. Thanks [/INST] Hello and welcome, Thanks for your query. It is a good thing appendicitis and hernia were ruled out, but hopefully through both a physical examination and an ultrasound investigation. As you have not mentioned an ultrasound investigation, I would advise you to go through with one, it is not painful at all, and can greatly help in visualizing any source, that could be causing your tenderness. The bloating could also be due to an irregular diet and unhealthy eating habits. Are you experiencing other symptoms like vomiting, or meal related pains (i.e. pain increases after a meal, or is relieved by a meal)? Has your stool changed in color or consistency? I understand we can only provide limited help to you without being able to directly communicate with you, I hope I have helped in some way or the other. You can always write back to us for further clarifications, and with more information. In the meantime, you could get an ultrasound done. Wishing you good health and lots of luck. Best regards. </s>
