My pelvis region right upper area has become swollen, but no pain at all and feel like something tubular when touched. Please advice in this regard.

You could have a. Couple things, from a hernia which is not incarcerated to significant gas and distention being trapped in your terminal small bowel from constipation large bowels. I would recommend getting it examined to be safe, as not many things present in the area but some can be serious. I hope that helps!
