Started 2 years ago, used to just happen when sitting for long periods of time i.e. a coach / flight, would develop groin pain also in area of right testicle / top inside right thigh. Would go within 24 hours with rest, sometimes eases with bowel movement. More recently having gone on active holidays it seems to develop after prolonged walking say after an hour and only goes away after rest. Initially thought this was down to change of diet / routine, was constipated and considered this an annoying holiday occurance but now tending to get this after any long period of walking. Appreciate thoughts.
