What Does Stabbing Pain Below The Breast After Abdominal Surgery Mean?

I had abdominal surgery 7 days ago, and there have been complications. I have a bleeding vein and have been order by my doctor to bed rest until the pain and bleeding stops. Last night I began having a stabbing pain below my breast on the right side and pain when breathing deep. It has gotten worse today. I am dizzy and weak (but have been since the surgery). Is this just muscle spasms and a possible rib dislocation from the CO2, or is this a blood clot? Should I go to the ER, or wait till my Dr office is open in the morning. The stabbing pain has gotten worse.
