I had my right ovary removed 4 days ago, due to a very bad ovarian torsion, caused by a 7.3 cm cyst. I ve been experiencing shoulder/chest pain due to gases, stomach pain that comes and goes, and I ve been alternating between Advil and Tylenol every four hours. The pain has slightly decreased, but I m suddenly feeling sharp, sudden pain on my lower right abdomen. I haven t been exercising or doing any activities, except for walking and maybe picking up certain things from the ground as carefully as I can. When I press on the right side, it just feels bloated and hurtful to touch. What is the reason for this?
