C-section wound is draining

I recently had a C-section 8 days ago and my wound has opened up and is draining a lot of fluid. Is this a big deal? My doctor gave me antibiotics.

Wow, this may be a big deal. I would go to the nearest ED and get seen by a doctor. Slight drainage can occur with an infection, but a lot of drainage is never good news. It may be that the entire wound has broken down and the fluid is coming from inside the abdomen. Go to the ED and you will need a god malpractice lawyer because the treatment for this is not antibiotics, but a visit back to the operating room. Please dump this fool of a surgeon. He/she is simply careless and negligent for giving you antibiotics without examining you or ordering an US test.
