Yesterday while moving a large tv I felt a pop in my lower abdomen.  I feel over backward and laid there in pain for about 30 seconds, short of breath.  After I got up it hurt to move up and down and out of our rocking chair.  Today it feels a little better, but Im worried it may be something more serious.
Hi. Thanks for your query and an elucidated history. Yes, it is a worrisome thing. Either there is a tear in the abdominal muscle and bleeding at a spot that is painful or can be a beginning of a hernia if your pain is situated at inguinal region. Take a strict rest till these gets healed up. Consult a Surgeon and get a clinical examination done. You may need an ultrasonography of the abdominal musculature to see the exact nature of injury you sustained.
