Do make an appt with your gynae soon and he'll be able to advise better
Hmm did you perhaps do any strenuous activity before that? Carry heavy loads, carry baby for very long period, baby wear, exercise/run etc? The c section site is still healing and will take several months to fully recover internally. Take things slower for now and hopefully that helps. However, if the pain is increasing in intensity and sharpness, or if there is fresh bleeding, do consult your doctor.
it may still be healing as it is still a fresh wound. But if pain is always there very frequently, u shd see a doc.
