Bad cough 4 weeks post c section

[charliekay]

Hi, I've recently had a bad cold which has now moved to my chest resulting in the worst cough I've ever had. I'm four weeks post c section and I was finally starting to feel normal again with no pain, but since I've had this cough the pain is back. I feel the same pain I did the first week after the section and now I'm worried that my internal scar may have opened!! I really have been coughing hard
Is it possible for a scar to open fours weeks later? And what symptoms would I have apart from pain? (Blood loss??)
