I just had a laparoscopic procedure done a few days ago to diagnosis and treat endometriosis. The doctor did find some spots and removed them, however, the doctor gave me "the warning" about air in the abdomen and how it can cause sever shoulder pain. I have been experiencing the shoulder pain along with a tightness in the chest. My question is, should I have this severe tightness in my chest with trouble taking deep breaths? How long until it goes away??
