<s>[INST] Hi, I m male 37 yrs old. I have been told that the inner stitches from my appendix taken out when I was 5 yrs old have somehow mended together. I m having discomfort on this side including internittent aches in thigh and less the calf muscle and the groin on the same area. Can this influence urination because during the last few weeks I ve been feeling a slight pain, almost the feeling of pressure. Any ideas? Thanks [/INST] Hello! Your history of appendicitis is not significant anymore as it was 32 year ago. Your symptoms are characteristic for urine tract infections and urine tract stones. That is why the first step you should take is to have urine test performed and abdomen ultrasound. The other reason of your chronic thigh and calf pain might be a Sciatic nerve compression. So if your pain does not go away for a long time you should have MRI of your backbone performed. Hope this will helpmate Care </s>
