Hi there I've had a pinching feeling in my groin for about 6 weeks it started after a terrible bout of straining due to really bad constipation ( sorry for tmi).... I went for a private ultrasound scan on my pelvis and right groin and he said all was fine bit he did see a 5mm lymph node near the tender area but looked normal and not suspicious.... I haven't had an illness that I know of  and have no idea why it would be there I still have pain there and just wondered if anyone had the same to put my mind at rest and if constant straining can cause it .... I'd be so grateful for a reply .... thank you
